Secure, multi-level access to obfuscated data for analytics

A computerized system comprising:

• a request processing module;
• and
• a protected enclave,
• wherein
• the request processing module is configured to:
• receive a user request to access data;
• identify an authorization level associated with a user request received;
• and
• via the protected enclave,
• obfuscate data with one or more obfuscation algorithms, the latter yielding different levels of obfuscation, and
• access obfuscated data corresponding to a user request, wherein the data are obfuscated with one or more of the obfuscation algorithms, so as to yield a level of obfuscation that is compatible with an authorization level identified, and
• in response to a user request, providing obfuscated data accessed via the protected enclave.

A computer program product for providing obfuscated data to users, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processors, to cause said one or more processors to:

• receive a request to access data from a user;
• identify an authorization level associated with the request received;
• via a protected enclave, access obfuscated data corresponding to the request received, wherein the data accessed have been obfuscated with an obfuscation algorithm yielding a level of obfuscation that is compatible with the authorization level identified, and
• provide, from the protected enclave, the obfuscated data accessed to the user.
