Abstract

An apparatus and method for controlling access to information based on content of the information and user identity. The apparatus includes a video display that displays the information to be viewable by one or more users. A user-recognition input device determines that an additional user is newly present in a given area having access to the display. A blocking device coupled to the user-recognition input device selectively blocks display of the information based on whether the additional user is newly present. In one embodiment, the user-recognition input device includes a video input device, and a feature recognition device operable to distinguish between two or more users based on one or more video features of the users. In another embodiment, the user-recognition input device includes an audio input device, and an audio feature recognition device operable to distinguish when an additional user arrives. In yet another embodiment, the user-recognition input device includes a movement-detection device operable to distinguish when an additional user arrives.

7. The apparatus according to claim 6, wherein the video content includes television programming.

8. The apparatus according to claim 6, wherein the video content includes computer-displayed text or graphics.

9. The apparatus according to claim 6, wherein the user-recognition input device includes a video input device, and a feature recognition device operable to distinguish between two or more users based on one or more video features of the users.

10. The apparatus according to claim 6, wherein the user-recognition input device includes a movement-detection device operable to distinguish when an additional user arrives.

11. A method for controlling access to information based on content of the information and user identity comprising the steps of:

displaying video information;

determining that a user is newly present with at least one further user in a viewing volume having access to the display of video information, including substantially continuously acquiring audio input signals from said viewing volume, and substantially continuously performing feature recognition on the audio input signals to determine when said newly present user arrives in said viewing volume;

storing information that identifies a video content that is being displayed on the video display, and information specifying which users are to be permitted access to that content;

comparing a user-identity value from the input device to the memory content specifying which users are to be permitted access to that content and producing an access-allowed indication based on a permitted access comparison; and

selectively controlling display of the content based on the access-allowed indication.

12. The method according to claim 11, wherein the video content includes television programming.

13. The method according to claim 11, wherein the video content includes computer-displayed text or graphics.

14. The method according to claim 11, wherein the step of determining includes acquiring video input, and performing feature recognition to distinguish between two or more users based on one or more video features of the users.

15. The method according to claim 11, wherein the step of determining includes detecting movement to distinguish when an additional user arrives.

16. A method for controlling access to information based on content of the information and user identity comprising the steps of:

outputting the information in a form discernable to a user;

determining, when at least one user is already present in a viewing volume having access to the information, that an additional user is newly present in the viewing volume, including substantially continuously acquiring audio input signals from said viewing volume, and substantially continuously performing feature recognition on the audio input signals to determine when the additional user arrives in the viewing volume; and

selectively blocking output of the information based on whether the additional user is newly present.

17. The method according to claim 16, wherein the step of determining includes acquiring video input, and performing feature recognition to distinguish between two or more users based on one or more video features of the users.

18. The method according to claim 16, wherein the step of determining includes detecting movement to distinguish when an additional user arrives.

19.
