Abstract: Techniques for improving systems for tracking data access are provided. A system for accessing and encoding data may, upon receiving a request for data, determine whether the data needs to be encoded for the purpose of tracking access to the data. If the system determines that the data needs to be encoded, the system may further determine the information which is to be encoded into the data, such as a client ID/user ID, timestamp, etc. The system may further determine an encoding scheme for the data such as a least significant bit algorithm. The system may further determine encoding data based on the encoding scheme and the information which is to be encoded into the data. The system may also encode the encoding data into the data based on the encoding scheme.
