Abstract
The system and methods described herein may be utilized to perform operations in a faster and less complex manner than provided by conventional systems. An encrypted record may be stored at a user device. The encrypted record may include entries related to operations that were previously requested by the user device. The encrypted record may have been encrypted using a dynamic value and a key that is associated with an entity associated with the user. A recipient computer of a request by the user device may be configured to utilize the dynamic value provided in the request and the key associated with the entity to derive the encryption key(s) last used to encrypt the record. The recipient computer may decrypt and modify the decrypted record to perform the requested operation while the user device is precluded from doing so.
