Abstract

A device includes a storage unit, a processor and an output unit. The storage unit is configured to store identification information and a plurality of temporary contact data items. The processor is configured to select one of the temporary contact data items based on the identification information and a first time index. The output unit is configured to output the selected temporary contact data item. The selected contact data item may include at least one of, e.g. a temporary telephone number, a temporary email address, a temporary IP address, and a temporary uniform resource identifier (URI).

Claims

1. A device, comprising:

identification information;

a storage unit configured to store the identification information and a plurality of temporary contact data items;

a processor configured to select one of the temporary contact data items based on the identification information and a first time index; and

an output unit configured to output the selected temporary contact data item.

2. The device of claim 1, wherein the temporary contact data items stored in the storage unit comprise data items generated from the identification information and second time indices.

3. The device of claim 2, wherein the processor is further configured to select the data items generated from the identification information and one of the second time indices identical to the first time index.

4. The device of claim 2, wherein the first time index and the second time indices respectively include a first time period number and second time period numbers, the second time period numbers being indicative of a series of predetermined time periods, respectively, and the first time period number being indicative of one of the series of predetermined time periods.

5. The device of claim 4, further comprising a clock, and wherein the first time period number is related to a current time of the clock.

6. The device of claim 1, wherein the processor comprises a random number generator configured to generate a random number based on the identification information and the first time index.

7. The device of claim 6, wherein the processor further comprises a temporary contact information selection unit configured to select one of the temporary contact data items based on the random number.

8. The device of claim 1, wherein the device comprises a clock, and the processor comprises a time conversion unit configured to determine the first time index based on a current time of the clock.

9. The device of claim 1, wherein the selected temporary contact data item comprises at least one of:

a temporary telephone number, a temporary email address, a temporary IP address, and a temporary uniform resource identifier (URI).

10. A method, comprising:

retrieving identification information from a storage unit, the storage unit storing a plurality of temporary contact data items;

selecting one of the temporary contact data items based on the retrieved identification information and a first time index; and

outputting the selected temporary contact data item as the temporary contact information.

11. The method of claim 10, wherein the temporary contact data items stored in the storage unit comprise data items generated from the identification information and second time indices.

12. The method of claim 11, wherein selecting comprises selecting the data items generated from the identification information and one of the second time indices identical to the first time index.

13. The method of claim 10, wherein selecting comprises:

generating a random number based on the identification information and the first time index; and

selecting one of the temporary contact data items based on the random number.

14. The method of claim 10, wherein the temporary contact information comprises at least one of:

a temporary telephone number, a temporary email address, a temporary IP address, and a temporary uniform resource identifier (URI).

15. A device, comprising:

a storage unit configured to store a plurality of actual contact data items of a plurality of respective communication devices in association with identification information of temporary contact information generating devices; and

a processor configured to;

receive temporary contact information,

generate identification information based on the temporary contact information and a first time index for the temporary contact information, the identification information identifying a particular one of the temporary contact information generating devices, and

retrieve one of the actual contact data items associated with the identification information from the storage unit.

16. The device of claim 15, wherein the processor comprises a time conversion unit configured to generate the first time index based on a time of receiving the temporary contact information.

17. The device of claim 15, wherein the storage unit is configured to further store a plurality of temporary contact information indices, and the processor comprises a temporary contact information index selection unit configured to retrieve one of the plurality of temporary contact information indices associated with the temporary contact information from the storage unit.

18. The device of claim 17, wherein the processor comprises an identification information generator configured to generate the identification information based on the retrieved one of the temporary contact information indices and the first time index.

19. The device of claim 15, wherein the retrieved temporary contact information comprises at least one of:

a temporary telephone number, a temporary email address, a temporary IP address, and a temporary uniform resource identifier (URI).

20. A method, comprising:

receiving temporary contact information;

generating identification information based on the temporary contact information and a first time index for the temporary contact information, the identification information identifying a temporary contact information generating device; and

retrieving, from a storage unit storing a plurality of actual contact data items of a plurality of respective communication devices, one of the actual contact data items associated with the identification information.

21. The method of claim 20, further comprising generating the first time index based on a time of receiving the temporary contact information.

22. The method of claim 20, wherein generating comprises:

retrieving, from the storage unit further storing a plurality of temporary contact information indices, one of the plurality of temporary contact information indices associated with the temporary contact information; and

generating the identification information based on the retrieved one of the temporary contact information indices and the first time index.

23. The method of claim 20, wherein the retrieved one of the plurality of the temporary contact information comprises at least one of:

a temporary telephone number, a temporary email address, a temporary IP address, and a temporary uniform resource identifier (URI).

24. The method of claim 20, wherein said one of the actual contact data items corresponds to actual contact information of one of the communication devices.
