COLLABORATIVE ARCHITECTURE FOR SECURE DATA SHARING

A device participates in a cyclical collaboration system. The device receives a request from a third party. A request value is determined that is associated with the request. A first random number is determined based on the first request value. The first random number is provided to a downstream device. A second random number is received that is generated by a upstream device. A first encrypted request value is determined based on the first request value, the first random number, and the second random number. The first encrypted request value is provided to a multiple party encryption subsystem. Encrypted request values generated by other participants of the cyclical collaboration network are received from the multiple party encryption subsystem. A validation score is determined based on the first encrypted request values and the encrypted request values received from the multiple party encryption subsystem.
