Abstract: Examples described herein relate to a manner of provide a time of life of data. In some examples, data and control parameters are received from a data source. The data can be encrypted and stored. In addition, at least a portion of the control parameters can be stored into a distributed ledger. In some examples, the portion of the control parameters include an indicator of expiration time of the data. In some examples, a data header for the data is generated, where the data header includes an indication that the data is subject to a limited life span and a data identifier. The data header can be accessed with a request to access the encrypted data. In some examples, a request to determine if the data is valid and accessible is provided to a node of the distributed ledger and an indication of whether the data is valid and accessible is received from a node in the distributed ledger.
