Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
190 words
A method for secure user access to a separate system having data stored in a memory device, comprising the following steps: establishing a first connection between a first communications device and an access device and transmission of a first code word from the first communications device to the access device; comparing the first code word with first authentication data stored in the access device; establishing a second connection between a second communications device and the access device, and transmitting a second code word form the second communications device to the access device; comparing the second code word with second authentication data stored in access device; transmitting a third code word from access device to the first communications device; transmitting the third code word from the first communications device to the second communications device; transmitting the third code word from the second communications device to the access device; and granting access to the system via at least one of the communications devices, given a valid third code word and the presence of a predetermined relationship between the first and second code words and the second authentication data stored in access device.
Claim 2
Independent Claim
190 words
A method for secure user access to a separate system having data stored in a memory device, comprising the following steps: establishing a first connection between a first communications device and an access device and transmission of a first code word from the first communications device to the access device; comparing the first code word with first authentication data stored in the access device; establishing a second connection between a second communications device and the access device, and transmitting a second code word form the second communications device to the access device; comparing the second code word with second authentication data stored in access device; transmitting a third code word from access device to the first communications device; transmitting the third code word from the first communications device to the second communications device; transmitting the third code word from the second communications device to the access device; and granting access to the system via at least one of the communications devices, given a valid third code word and the presence of a predetermined relationship between the first and second code words and the second authentication data stored in access device.
