Claim 12:
13. A method for a server to authenticate a request for access to a secure data file, comprising:
receiving a first login request and first login credentials from a first computing device, and in response to a match between the first login credentials and first stored credentials, returning a first security token to the first computing device;
receiving a request to decrypt the secure data file and geolocation information from the first computing device and sending a machine-readable optical label to the first computing device in response to said request to decrypt the secure data file;
receiving a second login request and second login credentials from a second computing device, and in response to a match between the second login credentials and second stored credentials, returning a second security token to the second computing device;
receiving geolocation information and decoded data of a scanned machine-readable optical label from the second computing device; and
validating said geolocation information from sand first computing device and said geolocation information from said second computing device by the server, and in response to successfully validating the geolocation information, linking the first and second security tokens, sending a link completion status indicator to the second computing device, and sending information to decrypt the secure data file to the first computing device.
