System and method for privacy policy enforcement

A method for privacy policy enforcement to ensure reconciliation between users communicating via an open system interconnection (OSI) communication architecture, the method comprising:

• receiving a privacy policy for at least one user's device;
• receiving a usage policy for at least one user, wherein the usage policy defines at least a first usage level and a second usage level, wherein the first usage level corresponds to a first privacy policy and the second usage level correspond to a second privacy policy;
• receiving encryption codes;
• receiving at least one dataset from a first user to be sent to a second user, wherein the at least one dataset comprises at least one data segment;
• encrypting by a first server the received data segments;
• receiving a privacy policy enforcement vector, having decryption keys corresponding to the encryption codes and configured to allow decryption of data segments corresponding to a match between the user policy and the usage policy;
• and
• performing selective decryption, by a second server, for each data segment, wherein data segments that correspond to a match between the privacy policy and usage policy are decrypted, and wherein at least one of the first server and the second server is external to the first user and second user.
