Abstract
Methods and apparatus to certify digital signatures are disclosed. An example method includes retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in a request to certify a digital signature, comparing the first geographical location associated with the identification number to a second geographical location to verify the second geographical location, and in response to the verification of the second geographical location and to a comparison of (a) biometric information associated with a user associated with the request and (b) stored biometric information, instructing a certificate issuer to certify the digital signature to indicate an authenticity of the digital signature.
