Abstract

The presently claimed invention relates generally to gaining access to secure systems. One claim recites an apparatus including: an image or video sensor for capturing image or video data; and a multi-purpose computer processor configured to: decode machine-readable information encoded in captured image or video data representing a plurality of physical objects, each instance of machine-readable information includes identifying information; determine an order in which the physical objects are presented to the image or video sensor for evaluation via the identifying information; and comparing the order to a predetermined sequence to determine whether to allow access to a remotely located computerized system. The apparatus may be housed, e.g., in a cell phone. Other combinations and claims are provided as well.

Claims

1. A method comprising:

employing a multi-purpose computer processor configured to;

decode machine-readable information encoded in each of a plurality of physical objects, each instance of machine-readable information including identifying information;

determine an order in which the encoded physical objects are presented for evaluation via the identifying information; and

comparing the order to a predetermined sequence to determine whether to allow access to a remotely located computerized system.

4. A programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 1.

5. A computer readable media comprising instructions stored thereon to cause a multi-purpose computer processor to perform the acts of claim 1.

2. The method of claim 2, wherein access is granted to the remotely located computerized system when the order and the predetermined sequence coincide in an expected manner.

3. The method of claim 2, in which said multi-purpose computer processor is further configured to:

determine an orientation of at least one physical object utilizing at least some orientation information provided in encoded information, and comparing the orientation information to a predetermined orientation to determine whether to allow access.

6. An apparatus comprising:

an image or video sensor for capturing image or video data;

a multi-purpose computer processor configured to;

decode machine-readable information encoded in captured image or video data representing a plurality of physical objects, each instance of machine-readable information includes identifying information;

determine an order in which the physical objects are presented to the image or video sensor for evaluation via the identifying information; and

comparing the order to a predetermined sequence to determine whether to allow access to a remotely located computerized system.

7. A cell phone comprising the apparatus of claim 6.

8. The apparatus of claim 6 in which the multi-purpose processor is executing to perform one of the functions recited in claim 6.

9. The apparatus of claim 6, wherein access is granted to the remotely located computerized system when the order and the predetermined sequence coincide in an expected manner.

10. The apparatus of claim 6, in which said multi-purpose computer processor is further configured to:

determine an orientation of at least one physical object utilizing at least some orientation information provided in encoded information, and comparing the orientation information to a predetermined orientation to determine whether to allow access.
