Secure storage and retrieval of data in a database with multiple data classes and multiple data identifiers

摘要

Secure storage and retrieval of data is provided with multiple data classes and data identifiers. Data values of a client are stored by receiving one or more authentication sets, at least one data value, an associated data class of the data value and a pseudo-random client value; calculating a data seed value based on the pseudo-random client value, a pseudo-random server value and the associated data class of the data value; generating a random data index value; generating a database index value based on the data seed value and the random data index value; storing the database index value; and providing the random data index value to the client. The client can be authenticated at the time of storage based on the one or more authentication sets. The authentication of the client and the storage of the data can be atomic such that only authenticated clients store the one or more data values. Techniques are also provided for the retrieval of stored data.
