Description
Technical Field
The invention relates to an intelligent photographing service method, system and storage medium for preventing portrait information from being revealed, and belongs to the technical field of photographing service.
Background
The human image information is also an important personal identification mark as an individual privacy source in the AI (artificial intelligence) era, becomes a key basis for verifying that the person is the person, and is closely related to people working, living, learning, examination, country departure and the like. The collection of certificate image information (namely, license) is a serious issue for protecting information security from the source. Because the requirements of license collection on illumination intensity (exposure), imaging distance (focal length), illumination angle, space, background and the like are high, the license collection standard is as high as tens of items, and people need to take a good picture and use the license simply and easily, the current photographing service has the following defects that the license is not easy to take a beautiful license which accords with the standard of the license:
1) The manual repair of the license acquisition source is not credible. When the original image is not good in effect, underexposure, shadow on the face and the like are required to be adjusted and optimized by means of manual image correction, in order to meet the aesthetic requirements of users, the original image can be beautified, even the biological characteristics of the human image are tampered, such as acne removal, skin beautifying, face thinning, mole correction, scar correction and the like, so that the risk of manual image correction distortion exists at the source of human image information acquisition, and the reality and credibility are difficult to ensure.
2) The license storage copy is prone to revealing and unsafe. Because the license collection requirement is high, the existing personal self-timer mode is difficult to meet, and therefore the license collection is mainly completed by a photo studio. The small-size photo album is operated, the technical equipment conditions are uneven, personal privacy such as portraits and identity information is controlled by the photo album, the personal privacy is stored, copied or transmitted on a network at will, and information security protection measures are lacked, so that the personal privacy can be possibly revealed no matter whether the personal privacy is credentials, student books or graduations.
3) The license interaction use mode is troublesome and inconvenient. The current license mode mainly provides satisfactory licenses by users, a business department is only responsible for information acquisition and verification of photo receipts, fingerprints, identity cards and the like, paper photos and receipts are easy to lose on hands of the users, a business acceptance window repeatedly acquires user information, and the interaction process of the licenses and the business departments requires the users to store complicated data, so that the business system is inconvenient to use.
4) The standard difference of the license is large and can not be used for one phase and multiple purposes. Because different certificates adopt different certificate making processes, each business department respectively establishes certificate standards, such as resident identification cards, inbound certificates, drivers' licenses and the like, and great differences exist in technical specifications of image acquisition of backgrounds, sizes, pixels, colors and the like, and the business departments do not realize interconnection sharing of certificate information and multiple purposes, so that a user needs to take a certificate and run a certificate point every time he/she has a certificate.
Therefore, the security risk exposed by the links of the image information acquisition and the interactive use of the credentials is lacking in special equipment which has low cost, is simple and easy to use and can prevent the image information from being revealed like a fingerprint acquisition instrument in the market, and the security and orderly image information acquisition and management are difficult to realize by the existing photographing service.
