El manejo seguro de los datos personales en el HC ( Historial Clínico ) de la CCSS


En un nuevo estudio publicado en The New England Journal of Medicine expone el caso de un hombre de 70 años de edad, que llegó a un hospital de Florida, y cuando fue atendido, los médicos encontraron tatuado en su pecho el mensaje “No resucitar”. 

¿Tú qué hubieras hecho?

La crónica la pueden leer en el siguiente link: https://www.cercp.org/…/articulos_docs_int…/nejmc1713344.pdf

El paciente tenía historial médico de obstrucción pulmonar crónica, diabetes mellitus y fibrilación auricular, según indica el reporte.
El paciente presentaba un alto nivel de consumo de alcohol, por lo que su estado de conciencia, no le permitía a los médicos obtener un veredicto sobre los deseos reales del mismo.
Inicialmente los médicos optaron por no hacerle caso al tatuaje, invocando el principio de no elegir un camino irreversible ante la incertidumbre.
El caso tuvo que ser visto por un comité de ética y después de un tiempo, aconsejaron al cuerpo médico, honrar el deseo del paciente, expresado a través de su tatuaje. "No resucitar (DNR) ".

Ellos sugirieron que era más razonable inferir que el tatuaje expresaba una preferencia auténtica, que lo que podría haber ser visto como una precaución también podría considerarse una ceremonia, y que la ley en ocasiones no es lo suficientemente ágil en estos temas, para apoyar el deseo real de los paciente. Casi en el mismo tiempo, el hospital recibió una notificación de un centro de salud de la Florida, en donde el paciente había hecho explícito dicho deseo.

Anoche en el tema de "Noches de Ciberseguridad" con Roberto Lemaître Picado se trato el tema de protección de datos personales. Link: https://www.youtube.com/watch?v=ug97XQihQwA
Hice el comentario que en la UE se han presentado muchos problemas con el acceso al HC ( Historial Clínico ) de los pacientes por parte de los Médicos.
Se supone que el acceso sólo debe ser en caso que se requiera para un tratamiento médico que lo admita. Muchos piensan que la 108 deja mucho de lado, la regulación de la big data en temas de salud y como la misma se trata.
Alejandro Esquivel, otro de los participantes en el programa, indicó que "Ese es un punto muy importante Ronald. Curiosamente en Costa Rica, la CCSS lo último que protege son nuestros datos personales.".
En casos como este de la Florida, el acceso a la datos de su HC ( Historial Clínico ), puede ser lo mejor para el paciente y liberar las acciones legales en contra del médico al realizar una acción que considera deslegitimada.

El el juramento hipocrático original, realizado por los primeros médicos dice: "Guardaré secreto sobre lo que oiga y vea en la sociedad por razón de mi ejercicio y que no sea indispensable divulgar, sea o no del dominio de mi profesión, considerando como un deber el ser discreto en tales casos."
En oficio de este principio, todo HC debería ser destruido automáticamente, cuando el paciente fallezca.
Muchos países del mundo están adoptando el convenio 108 elaborado en la UE, como base para el tratamiento de datos personales.

El Convenio para la Protección de las Personas con respecto al Tratamiento Automatizado de Datos de Carácter Personal (“Convenio 108”) y su Protocolo Adicional relativo a las Autoridades de Control y a los Flujos Transfronterizos de Datos, fue modificado en mayo del 2018 en la Unión Europea.

La Directiva protege el derecho fundamental de los ciudadanos a la protección de datos cuando los utilizan las autoridades policiales. Garantiza que los datos personales de víctimas, testigos y sospechosos de delitos sean debidamente protegidos, y facilita la cooperación transfronteriza en la lucha contra la delincuencia y el terrorismo. Inicialmente este apartado había sido enviada a revisión, pero luego de los atentados ocurridos en París en el 2015, obtuvo un nuevo impulso.
El asunto, es que la norma, hasta donde he visto y con la lecturas publicadas por otros estudiosos del tema, presenta grandes omisiones con respecto al tema del resguardo de información en los centros de salud. Parece haber un vacío normativo en este tema.
En INTERNET, tenemos el derecho al olvido. Este es una vertiente del derecho a la cancelación y consiste en el derecho a ser ‘desindexado’ de lo públicamente disponible.
Para México representa que la protección de los datos personales y la privacidad constituyen un derecho fundamental. En materia de derechos digitales, como el derecho al olvido, México cuenta con los llamados Derechos ARCO, que consisten en Acceso, Rectificación, Cancelación y Oposición de los datos personales en posesión tanto de organismos públicos como de particulares, establecidos en el Artículo 16 constitucional, así como con la Ley Federal de Protección de Datos Personales en Posesión de Particulares.
En el caso de Costa Rica, Publicada en La Gaceta n.º 170 de 05 de setiembre de 2011, LA ASAMBLEA LEGISLATIVA DE LA REPÚBLICA DE COSTA RICA DECRETA: PROTECCIÓN DE LA PERSONA FRENTE AL TRATAMIENTO DE SUS DATOS PERSONALES
..." El régimen de protección de los datos de carácter personal que se establece en esta ley no será de aplicación a las bases de datos mantenidas por personas físicas o jurídicas con fines exclusivamente internos, personales o domésticos, siempre y cuando estas no sean vendidas o de cualquier otra
manera comercializadas."

En el caso de los HC, son instituciones públicas las que manejan dichos datos, por tanto, no esta fuera de lo que se determina en al artículo 2 del capítulo I de Disposiciones Generales de la Ley Nacional.
Por tanto, basado en lo que expresa el artículo 1 de la Ley: "Esta ley es de orden público y tiene como objetivo garantizar a cualquier persona, independientemente de su nacionalidad, residencia o domicilio, el respeto a sus derechos fundamentales, concretamente, su derecho a la autodeterminación informativa en relación con su vida o actividad privada y demás derechos de la personalidad, así como la defensa de su libertad e igualdad con respecto al tratamiento automatizado o manual de los datos correspondientes a su persona o bienes.", todos los costarricenses podemos y deberíamos, si mi interpretación es la correcta, obligar a la instituciones de salud en Costa Rica, específicamente a la CCSS, el borrado absoluto de nuestro HC y dar fe de dicha acción.
Creo que Roberto Lemaître Picado nos puede explicar con mayor criterio, si lo que digo es una burrada o estoy en lo correcto. (-Ya nos dijo que lo iba a analizar y nos estaría comentando.- )

Por el momento, que sirva todo esto para abrir la discusión y poner el tema sobre el tapete.

Redwood Shores, Calif.—Jan 29, 2019 

The MINA Group is continually testing the boundaries of restaurants and opportunities to transform the fine dining experience, bringing new flavors to customers across the world. No better example of this philosophy is the group’s innovative The Street Food Hall concept in Waikiki, Hawaii. Powered by the Oracle Food and Beverage Simphony restaurant management platform and Oracle MICROS 600 series point-of-sale devices, the hall brings together 10 globally-inspired food stations, enabling visitors to taste multiple cuisines in a casual, festive setting. 

An ambitious project aimed at providing an ever-changing dining experience for guests, MINA Group operates each of these stations separately led by individual chefs with an evolving menu.

Oracle Utilities Opower Innovations Help Utilities Connect with Every Customer




Press Release 

With more than 100 enhancements to the Opower platform, Oracle empowers utilities to better engage customers as they turn to diverse and dynamic energy sources and rate programs 

Redwood Shores, Calif.—Jan 29, 2019 

The Oracle Utilities Opower customer engagement platform now includes four entirely new experiences and over 100 innovations for utilities to connect with every residential customer. These enhancements deliver measurable results at scale: cost-effective energy savings, satisfied customers, lower service costs, new revenue streams, and more connected homes. 

“With the rise in dynamic rates, complex bills, and consumer technology on the grid edge, serving the diverse needs of today’s utility customers is becoming increasingly complex,” said Dan Byrnes, SVP of product development, Oracle Utilities. “Point solutions only serve small pockets of customers. With the latest release of the Opower platform, utilities can connect with every customer to increase engagement and satisfaction, drive down service costs, and balance demand on the grid.” 

Since breaking onto the scene more than a decade ago, the Opower platform has continued to stand as the most complete and effective customer engagement platform in the utility industry. This latest release expands Opower even further with four new digital customer experiences. Each new offering leverages machine learning to render actionable energy insights, and experimental program design to deliver measurable results. 

“Oracle’s latest improvements to its Opower platform demonstrate the company’s ability to continue distinguishing itself as a leader in home energy management, as well as its commitment to innovation and helping customers achieve savings as scale,” says Paige Leuschner, research analyst at Navigant Research. 

The new experiences include:

· Behavioral Load Shaping: a personalized, digital experience that enables utility customers on dynamic rates to shift their energy use away from daily peaks and control their complex bills.
· Digital Self Service Transactions: a suite of embeddable web and mobile features for utility customers to start service, pay their bills and manage their accounts, all natively integrated with Oracle Utilities’ market-leading customer information system (CIS).
· AMI Customer Education Reports: multi-channel reports to educate and engage utility customers during a smart meter rollout, with new insights and recommendations for managing their energy use.
This release also includes more than 100 new features to amplify demand side management and customer care results, including:

· Embedded Web 2.0 Insights: Visual energy insights for utility web and mobile apps now render with more speed, reliability, and styling control than ever before to improve time on site by 25 percent.
· Unauthenticated Online Audits: Frictionless online audits allow customers to securely access the Opower audit with a single tap or click and potentially double their behavioral energy savings.
· Dynamic Campaigns: Platform tools to rapidly curate targeted marketing across the Opower experience and drive adoption of utility programs and products—such as connected home devices—at up to a 61 percent higher rate than traditional and digital advertising.
· Proactive Billing Alerts: With new weather insights, dual fuel support, and customer-set budget goals, these upgraded alerts deliver digital energy savings and reduce high bill calls by up to 22 percent.
· Connected Home and Enterprise Integrations: Mature APIs and a growing library of integrations into Oracle customer, meter, and marketing applications and third-party connected home platforms make it easy to plug Opower into core utility operations, engage customers through digital assistants, and enable smart home device control. 
“Customers trust their utility for advice how to: save energy, control their bills, adopt new technologies and use them well. With these new innovations, we’re helping utilities connect it all for their customers,” said Byrnes. “And we’re just getting started.”

New Oracle Utilities Opower Cloud Service Enables Utilities to Engage Customers at the Grid Edge




Press Release 

Aids utilities in becoming trusted advisors to customers adopting solar and other distributed energy resources 

Redwood Shores, Calif.—Jan 29, 2019 

As emerging energy sources—such as solar—compel customers to become more active participants in the grid, their energy management needs are getting more complex. Oracle is equipping utilities to serve as trusted advisors to these increasingly active customers with its new Oracle Utilities Opower Distributed Energy Resources Customer Engagement Cloud Service. 

Available today, the offering initially provides rooftop solar customers helpful insight into their utility bills and energy savings and will expand to address other types of distributed energy resources (DERs) in the future such as electric vehicles and residential battery storage. 

Oracle Utilities Opower DER Customer Engagement is one of four new products and more than 100 new features in the Opower platform, the industry’s leading suite of customer engagement and energy efficiency cloud services. To learn more, visit today’s release here

According to Wood Mackenzie, “Solar is the second fastest growing resource after natural gas in the U.S., and residential solar has grown by 500+MW every quarter over the last four years.” However, many early adopters have been dismayed with their expectation of utility bill savings versus the reality. This is resulting in an influx of calls to their utility provider, which have proven to be up to $8 more expensive and considerably longer than non-solar related calls. 

Based on extensive research into the solar customer journey, Opower DER Customer Engagement addresses these challenges by providing utility customers with a personalized set of insights and recommendations relating to their overall energy generation, usage, and resulting bill. 

“Engaging with our customers and providing them clear, consistent information about their energy consumption and production is critical,” said Feltrin Davis, Manager, Business Intelligence and Data Analytics Smart Energy Services, Exelon. “With Oracle, we have been able to regularly deploy new web tools for our solar/net energy meter customers and are updating them frequently to ensure we are providing the best experience possible.” 

With Opower, Utilities can now send new solar customers onboarding communications explaining what to expect and how solar billing works. And new or existing customers can leverage online tools and insights to understand their net energy consumption. In addition, solar customers will also have a simple overview of their bills and a comparison of how their energy costs have changed since adopting solar. As a result, customers are happier and utilities reduce expensive call center volume. 

“As distributed energy resources continue to rise, consumers are becoming more active and in control of their energy footprint – both as users and producers,” said Dan Byrnes, SVP of product development, Oracle Utilities. “They are looking to their utility to help guide them throughout this journey and provide the clear, accessible insights they need to make more informed decisions. This innovation is a critical step forward in enabling the kind of deeper relationship between utilities and their customers which is essential as the industry moves towards a more customer-centric grid model.” 

This offering—the only of its kind on the market—is powered by the world’s largest residential energy data analytics platform with over 1.6 trillion meter reads from more than 60 million households and businesses, across 100 utilities.

Controlling Your Cloud - Uploading Large Files To Oracle Object Storage

By TODD SHARP, Oracle Blogs.

In my last post, we took an introductory look at working with the Oracle Cloud Infrastructure (OCI) API with the OCI Java SDK. I mentioned that my initial motivation for digging into the SDK was to handle large file uploads to OCI Object Storage, and in this post, we'll do just that. 

As I mentioned, HTTP wasn't originally meant to handle large file transfers (Hypertext Transfer Protocol). Rather, file transfers were typically (and often, still) handled via FTP (File Transfer Protocol). But web developers deal with globally distributed clients and FTP requires server setup, custom desktop clients, different firewall rules and authentication which ultimately means large files end up getting transferred over HTTP/S. Bit Torrent can be a better solution if the circumstances allow, but distributed files aren't often the case that web developers are dealing with. Thankfully, many advances in HTTP over the past several years have made large file transfer much easier to deal with, the main advance being chunked transfer encoding (known as "chunked" or "multipart" file upload). You can read more about Oracle's support for multipart uploading, but to explain it in the simplest possible way a file is broken up into several pieces ("chunks"), uploaded (at the same time, if necessary), and reassembled into the original file once all of the pieces have been uploaded. 

The process to utilize the Java SDK for multipart uploading involves, at a minimum, three steps. Here's the JavaDocs for the SDK in case you're playing along at home and want more info. 
Initiate the multipart upload 
Upload the individual file parts 
Commit the upload 

The SDK provides methods for all of the steps above, as well as a few additional steps for listing existing multipart uploads, etc. Individual parts can be up to 50 GiB. The SDK process using the ObjectClient (see the previous post) necessary to complete the three steps above are explained as such: 

1. Call ObjectClient.createMultipartUpload, passing an instance of a CreateMultipartUploadRequest (which contains an instance of CreateMultipartUploadRequestDetails) 

To break down step 1, you're just telling the API "Hey, I want to upload a file. The object name is "foo.jpg" and it's content type is "image/jpeg". Can you give me an identifier so I can associate different pieces of that file later on?" And the API will return that to you in the form of a CreateMultipartUploadResponse. Here's the code: 

So to create the upload, I make a call to /oci/upload-create and pass the objectName and contentType param. I'm invoking it via Postman, but this could just as easily be a fetch() call in the browser:



So now we've got an upload identifier for further work (see "uploadId", #2 in the image above). On to step 2 of the process:

2. Call ObjectClient.uploadPart(), passing an instance of UploadPartRequest (including the uploadId, the objectName, a sequential part number, and the file chunk), which receives an UploadPartResponse. The response will contain an "ETag" which we'll need to save, along with the part number, to complete the upload later on.

Here's what the code looks like for step 2:

And here's an invocation of step 2 in Postman, which was completed once for each part of the file that I chose to upload. I'll save the ETag values along with each part number for use in the completion step.



Finally, step 3 is to complete the upload.

3. Call ObjectClient.commitMultipartUpload(), passing an instance of CommitMultipartUploadRequest (which contains the object name, uploadId and an instance of CommitMultipartUploadDetails - which itself contains an array of CommitMultipartUploadPartDetails).

Sounds a bit complicated, but it's really not. The code tells the story here:

When invoked, we get a simple result confirming the completion of the multipart upload commit! If we head over to our bucket in Object Storage, we can see the file details for the uploaded and reassembled file:

And if we visit the URL via a presigned URL (or directly, if the bucket is public), we can see the image. In this case, a picture of my dog Moses:



As I've hopefully illustrated, the Oracle SDK for multipart upload is pretty straightforward to use once it's broken down into the steps required. There are a number of frontend libraries to assist you with multipart upload once you have the proper backend service in place (in my case, the file was simply broken up using the "split" command on my MacBook).
