1. An apparatus to validate a request to certify a digital signature, the apparatus comprising:
- a data transceiver to receive the request to certify the digital signature from a user and to receive first information about a first physical characteristic of the user;
a biometric authenticator to compare the first information about the first physical characteristic of the user to first stored physical characteristic information;
a location authenticator to verify a second geographical location identified in the request by retrieving a first geographical location associated with an identification number identified in the request and associated with a network device from a first database, comparing the first geographical location associated with the identification number to the second geographical location, and determining that the first geographical location matches the second geographical location; and
a certificate issuer to certify the digital signature to indicate an authenticity of the digital signature based on the comparison of the first information about the first physical characteristic to the first stored physical characteristic information and the verification of the second geographical location.

12. A tangible storage device or storage disc comprising instructions which, when executed, cause a machine to perform a method comprising:
verifying a second geographical location identified in a request to certify a digital signature by; retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in the request, the network device associated with a user; comparing the first geographical location associated with the identification number to the second geographical location identified in the request; and certifying the digital signature to indicate an authenticity of the digital signature when the first geographical location matches the second geographical location. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method to certify a digital signature, the method comprising:
-
comparing biometric information associated with a user to stored biometric information; verifying a second geographical location identified in a request to certify the digital signature by; retrieving, from a first database, a first geographical location associated with an identification number associated with a network device and identified in the request; comparing the first geographical location associated with the identification number to the second geographical location; and determining that the first geographical location matches the second geographical location; and certifying the digital signature to indicate an authenticity of the digital signature based on the comparison of the biometric information to the stored biometric information and the verification of the second geographical location. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
