A computer-implemented system and method for encrypting call recordings is provided. Calls are recorded and each call recording is divided into segments. Each segment represents a record. An encryption key unique to each call recording is generated. The unique encryption keys each include seed information from two or more sources and a key counter for one such call recording. For each record, an encryption counter is encrypted using the encryption key for the call recording associated with that record. Also, for each record, the encrypted encryption counter and the data from that record are mixed and encrypted.
