Abstract: An online service provisioning process is provided during which the service provider's knowledge about the user to whom the service is delivered does not increase. This is accomplished by presenting user attribute information to the service provider as obfuscated objects that can be independently verified and which are privacy preserving.

Abstract: Applications of the privacy switch technology are shown for handling data breaches in database systems, thereby providing fundamental improvements to the security and utility of database technology.

Abstract: A method for communicating information relating to test results of a user includes obtaining test results of a user. An assertion is derived from the test results of the user. The test results are input to a pre-provisioned first algorithm. The assertion is encapsulated in a first data object by a PGE that controls an environment in which the first algorithm is executed. A first proof is generated which is configured to be usable to verify that the first algorithm used the test results to produce the assertion when provided to a PVE along with the first data object. The test results itself are excluded from the first proof and the first data object such that privacy of the test results is maintained. The first proof and the first data object are communicated to a receiving communication device from an enterprise communication device associated with the user and an enterprise.

Abstract: Systems and techniques described herein are concerned with providing supervisory control of computer programs. In particular, a method for executing application code defining a computer program includes providing a “kill switch” to the operator, which allows the operator to disable the computer program. The kill switch is configured so that the computer program is incapable of over-riding it.
