Abstract
A method for authorizing access to a first computing device is provided. The method comprises the first computing device forming a challenge, encoding the challenge into a symbol, and displaying the symbol. The first computing device receives a request for access from a user. Access to the first computing device is allowed in response to provision of an access code to the first computing device by the user. The access code is formed by a server in response to capturing the symbol, decoding the symbol into the challenge, forming a request from the challenge, and providing the request to the server. The server forms a decision to allow access by the user to the first computing device.
Claims4
A method for authorizing access to a first computing device, the method comprising performing, at a second computing device, the steps of:
- capturing a symbol from the first computing device;
- decoding the symbol into a challenge;
- generating a request from the challenge;
- and
- providing the request to a server, wherein a second computing device performs the steps of the capturing and the decoding of the symbol and the generating and the providing of the request, and wherein the challenge comprises an identifier of the first computing device, a server address and a function differentiating challenges formed at different times.
Apparatus for obtaining secure access to a first computing device, the apparatus comprising:
- a memory;
- and
- at least one processor coupled to the memory, operative to capture a symbol from the first computing device, decode the symbol into a challenge, generate a request from the challenge, form a decision to allow access to the first computing device, and form an access code, wherein the symbol comprises an identifier of the first computing device and an address of the at least one processor, wherein the challenge comprises the identifier of the first computing device and the address of the at least one processor and wherein the request comprises the first computing device identifier.
An article of manufacture for obtaining secure access to a computer device, wherein the article comprising a computer readable storage medium having one or more programs embodied therewith, wherein the one or more programs, when executed by a computer, perform steps of:
- capturing a symbol from the first computing device;
- decoding the symbol into a challenge;
- generating a request from the challenge;
- and
- providing the request to a server, wherein the a second computing device performs the steps of the capturing and the decoding of the symbol and the generating and the providing of the request, and wherein the challenge comprises an identifier of the first computing device, a server address and a function differentiating challenges formed at different times.
