Methods and apparatuses for verifying data records by a verification service provided in a distributed ledger are disclosed. The distributed ledger receives a digital signature from a data storage, the digital signature being computed for the data record at the time of storing the data record in the data storage. The digital signature is stored separately from the data record in the distributed ledger for later use in determining whether the data record has been altered since the storing of the data record in the data storage. The digital signature is communicated from the distributed ledger to at least one user device for use in determining whether the data record has been altered since the storing of the data record.
