Graphic data alteration to enhance online privacy

摘要

A computer alters at least one recognizable metric or text in a digitally-encoded photographic image by operating an alteration algorithm in response to user input data while preserving an overall aesthetic quality of the image and obscuring an identity of at least one individual or geographic location appearing in the image. An altered digitally-encoded photographic image prepared by the altering of the at least one recognizable metric or text in the image is stored in a computer memory. User feedback and/or automatic analysis may be performed to define parameter values of the alteration algorithm such that the alteration process achieves preservation of aesthetic qualities while obscuring an identity of interest.

主权项

1. A method, comprising:
altering selected facial recognition metrics in a digitally-encoded image of a person, by a computer operating an alteration algorithm that identifies an alteration of the selected facial recognition metrics based on a value ofΔ=∑1⁢⁢to⁢⁢M⁢∂i_calculated to substantially reduce risk of automatic recognition of the person while preserving an overall aesthetic quality of the image, wherein δi is a measure of metric alteration of each of a number M of the selected facial recognition metrics; and
storing, in a computer memory, an altered digitally-encoded image prepared by the altering of the selected facial recognition metrics in the digitally-encoded image.
