Abstract

Disclosed herein are databases that contain image context categorizations, those categorizations identifying the context of an image based on a computed fingerprint. Also disclosed herein are applications of such a database, including a viewing application that blocks the rendering of images with undesirable content noted by a content categorization, and a scanning application that locates images in a corpus or repository of images having certain content noted by content categorization, such as unlawful images. Such blocking may be through an obfuscation technique, such as blurring, distorting an image, or may be through a replacement of image material. A categorization tool may include obfuscation with an aperture tool for clarifying portions of blocked images. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

Claims

1. A computer-readable medium containing instructions for selectively rendering images according to categorization content, said medium comprising computer instructions executable to achieve the functions of:

accessing a store of informational content including images;

fetching images located in the store;

for fetched images, computing a fingerprint;

accessing a store of content categorizations, said accessing requesting a content categorization for a computed fingerprint;

receiving from the store in response to a request for a content categorization, a data object containing at least one content categorization;

making a determination as to whether an image is to be rendered based on a data categorization from the store using a fingerprint corresponding to the image;

if it is determined that an image should be rendered based on a categorization of that image, displaying the image to a person;

if it is determined that an image should not be rendered based on a categorization of that image, performing a non-rendering step.

2. A computer-readable medium according to claim 1, wherein the non-rendering step is to render a obfuscated copy of the image.

3. A computer-readable medium according to claim 1, wherein the non-rendering step is to omit rendering of the disallowed image.

4. A computer-readable medium according to claim 1, wherein the non-rendering step displays a message where the image would have appeared.

5. A computer-readable medium according to claim 1, wherein the non-rendering step displays a pre-selected background image or pattern.

6. A computer-readable medium according to claim 1, wherein said computer instructions are further executable to achieve the function of operating an HTML browser.

7. A computer-readable medium according to claim 1, wherein said computer instructions are further executable to achieve the function of displaying data from untrusted sources.

8. A computer-readable medium according to claim 1, where a determination is made as to whether an image should be rendered is based on a content category selected from the group consisting of sexual content, violence, nudity, and child pornography.

9. A computer-readable medium according to claim 1, wherein said computer instructions are further executable to achieve the functions of creating of submitting an image content categorization to the store of categorizations.

10. A system for selectively rendering images according to categorization content, comprising:

a display viewable by a person;

an image access facility functional to read a store of informational content including images;

a content categorization facility functional to read a database of image content categorizations;

a fingerprint computation facility functional to produce fingerprints from image data;

a rendering facility functional to display information retrieved through said image access facility on said display;

wherein said system is operable to receive a fingerprint from said fingerprint computation facility for an image obtained through said image access facility;

wherein said system, having received a fingerprint for an image from said fingerprint computation facility, is further operable to obtain a content categorization through said content categorization facility;

wherein said system, having obtained a content categorization for an image through said content categorization facility, makes a determination as to whether or not the image is appropriate to display;

wherein said system renders an image through said rendering facility where a corresponding appropriateness determination is positively made for the image; and

wherein said system takes a non-rendering step for an image where a corresponding appropriateness determination is negatively made.

11. A system according to claim 10, wherein said content categorization facility is functional to access a plurality of content categorization databases.

12. A system according to claim 11, wherein said content categorization facility is functional to select a content categorization database by a hash of a fingerprint.

13. A system according to claim 11, wherein said content categorization facility is functional to select a content categorization database by a hash of a fingerprint.

14. A system according to claim 10, wherein said content categorization facility is functional to access a distributed content categorization database.

15. A system according to claim 10, wherein said fingerprint computation facility uses a function having image modification immunity.

16. A system according to claim 10, wherein said system is further functional to submit an image content categorization to a database of image content categorizations.

17. A method of selectively rendering images according to categorization content, said method comprising the steps of:

accessing a store of informational content including images;

fetching images located in the store;

for fetched images, computing a fingerprint;

accessing a store of content categorizations, said accessing requesting a content categorization for a computed fingerprint;

receiving from the store in response to a request for a content categorization, a data object containing at least one content categorization;

making a determination as to whether an image is to be rendered based on a data categorization from the store using a fingerprint corresponding to the image;

if it is determined that an image should be rendered based on a categorization of that image, displaying the image to a person;

if it is determined that an image should not be rendered based on a categorization of that image, performing a non-rendering step.
