SECURE STORING AND RETRIEVAL OF SENSITIVE DATA FROM A SERVER SYSTEM

原文（中文）

A method includes receiving a request from a data requester device by a server system to retrieve sensitive data associated with a customer. Decryption of the sensitive data can require a composite decryption key specific for the encrypted sensitive data. The method can include retrieving the encrypted sensitive data, a login session identifier associated with the encrypted sensitive data, at least one attribute associated with the data requester, and a decryption algorithm. The login session identifier, the at least one attribute associated with the data requester, and the decryption algorithm are required for generating the composite decryption key for decrypting the encrypted sensitive data. The method includes generating the composite decryption key and decrypting the encrypted sensitive data by the server system based on the composite decryption key. The method can include providing the decrypted sensitive data to the data requester device to be revealed.
