The e-signature is applied to the data within a software system, or in a hardware security module, or some other computing device. The Land Registry will build the capabilities for electronic signatures to create digital mortgages , it said in a blog post . To comply with EU regulations , e - signatures must be uniquely linked to the signatory , must be capable of identifying the signature , must be created using software that only the signatory can control , and must be linked to the signed data in such a way that any subsequent change in data is detectable . By EU law , an e - signature can not be witnessed , so its certification instead lies in the integrity of the data that has been signed .
