Description

Technical Field
The invention relates to the technical field of privacy processing, in particular to a privacy decision recommendation system based on image data and deep learning.
Background
Currently, with the development of social networks and smart phone technologies, people can conveniently share images taken at will in the social networks. However, such sharing, if not controlled or directed, may cause various privacy leaks, serious or even personal injuries or infringements, various cyber crime or fraud. As indicated by relevant research studies, many teenagers prefer to share or dazzle their own, friends or classmates of private photos on social networks, and a great lack of knowledge in doing so can cause various privacy leaks, and in some cases even lifelong negative effects or injuries. It is also reported that 78% of network-related perpetrators use social networking media to locate victims. The perpetrator can inquire or deduce various information of the victim according to the social network picture (and the related auxiliary information). The current social network sites do not provide an effective privacy decision recommendation tool for common users (especially teenagers) to use, and remind the users to make decisions for use by the users or a social network access control system when the users publish social network images. Therefore, there is a need to develop a privacy decision recommendation method and system for social network digital image sharing.
In the prior art, privacy protection of images in a social network is mainly achieved through user-defined access control authority, anonymization processing, image encryption, burning after reading and the like.

The invention provides an image source-only social network decision model based on image-text matching deep learning, and solves the problems of automatic understanding and difficult matching of privacy semantics of complex digital images. The invention provides a multi-source social network privacy decision-making model based on multi-mode deep learning, and solves the problem of difficulty in image privacy and semantic joint analysis in a complex and diversified social environment. The invention provides and designs a privacy protection method based on a random corresponding mechanism, and solves the problem of risk leakage of user training data privacy of a deep learning privacy decision model.

a privacy determination module: the setting standard used for obtaining the setting of different privacy levels set by the user according to the historical privacy setting information of the user; wherein
The setting criteria include: the method comprises the steps of obtaining picture content standards, social type standards and picture storage position standards;
the historical privacy setting information of the user is information set by pre-acquiring the historical privacy of the user, and then judging the type and standard of the set privacy information; for example: when a user uses a life photo of the user as privacy, if the life photo of the user is related to the life photo of the user in the picture content, the life information is the standard of the picture content, the life information can be 2-level privacy, in addition, some pictures can be the work content of the user, the work of the user can be 1-level privacy content, the social type standard can be different social channels such as WeChat and relatives, the social channel can be 2-level privacy of the social type, encrypted places can exist in a mobile phone of the user, and the encrypted places can belong to 3-level privacy of the user;
a classifier building module: establishing a picture classifier based on picture information extraction according to the set standard; wherein the content of the first and second substances,
the picture information includes: an image surface information classifier, a social type classifier and a picture storage classifier;
the image classifier for extracting the image information is also a classifier for dividing the information through the image; the image surface information classifier classifies information according to picture surface display elements. For example: the pictures are used for working in a working place, and the classification types are used for working; and when the picture surface display element is a forest, the classified type may be landscape. The social type classifier determines what type of social channel is according to the elements on the picture.
The picture classifier includes: an information content classifier and a picture type classifier;
a sample screening module: screening historical privacy data of the user according to the picture classifier, and determining a social privacy sample;
a grading module: the privacy awareness and trust calculation method is used for carrying out privacy awareness calculation and privacy trust calculation on different social privacy samples, dividing privacy grades according to calculation results and determining the social privacy samples with different social privacy grades; wherein the content of the first and second substances,
the social privacy sample comprises: low risk privacy samples, medium risk privacy samples, and high risk privacy samples. The privacy consciousness calculation is that a user sets privacy characteristics according to a judgment standard for privacy, a screening model is established through the privacy characteristics, and privacy consciousness is determined through the screening model judgment; and then, calculating the trust degree through establishing a privacy entropy calculation and then calculating the trust degree through the privacy entropy value.
The principle of the technical scheme is as follows: in the prior art, the problem is that when the privacy samples are obtained, the sample data are few, so the scheme adopted by the invention is that the privacy data of different levels are divided in a classifier mode, classified storage is carried out after division, and all the privacy samples can be determined by calculating privacy consciousness and privacy trust based on user habits for the classified and stored different social privacy samples.
Example 3:

A data preprocessing unit: the system is used for preprocessing the user data and determining semantic content of the user data; wherein the content of the first and second substances,
the pretreatment comprises the following steps: the image-text conversion processing (namely converting the image content into characters), the word segmentation processing (if the characters exist in the image or the text, the characters are segmented and are divided into a plurality of technical nouns for processing), the privacy labeling processing (namely labeling the privacy content in the image), the TF-IDF processing (belonging to the text mining technology and being the privacy of five users in a user terminal) and the image named entity classification processing (namely after the image has specific classification, the image is classified by specific classification names);
a calculation unit: carrying out privacy consciousness calculation on the semantic contents to determine a privacy consciousness value, and carrying out privacy trust calculation on the semantic contents to determine a privacy trust value; this is different from the privacy awareness calculation of the privacy sample in embodiment 3, which is to calculate the privacy content for each privacy content, and further calculate the privacy trust value according to the privacy content. The privacy trust value is whether the private content is trustworthy or not, and whether the private content is truly private or not. The privacy awareness value is a value obtained by calculating the image content, and determining whether or not the image content is private, what the privacy level is, and what the privacy level value is the privacy awareness value.
A grade division unit: establishing a binary decision tree according to the privacy trust value and the privacy consciousness value, determining the sensitive values of different image data, and dividing privacy grades according to the sensitive values; the sensitive value is also a privacy value of the privacy content for the user, that is, a value with a low degree of privacy.
The privacy classes include: low risk privacy, medium risk privacy, and high risk privacy;
the sensitive value has a corresponding sensitive value threshold according to the privacy level.
According to the invention, the deep learning models with different privacy levels are required to be established, so that a plurality of samples are required to be obtained, the image data is obtained through establishing the API interface, the image data is processed, the privacy data is divided according to different privacy levels based on the processing result, and the privacy division is based on the sensitive value which is mainly divided artificially. The invention can not only analyze single or multiple images of the social network to obtain individual privacy, but also analyze single or multiple images (and environment information such as related texts) published in forums, social networks or other environments of the internet to obtain information in various fields such as national relevant politics, economy, military and the like, and the invention only establishes a model by an API interface.
In a particular embodiment, the method further comprises: determining a value of privacy awareness is calculated by:
step 1: judging whether the semantic content conforms to the privacy content or not according to the semantic content:
Figure BDA0003515898960000131
wherein, P (P)i) Represents a privacy value; q represents a history privacy type determination coefficient; w represents a history privacy content determination coefficient; k is a radical of formulaiA type feature representing the ith image data; p is a radical ofiSemantic features representing the ith image data; p (Q | k)i) The judging function is used for judging whether the type characteristics of the ith image data accord with the privacy type judging coefficient or not and determining a privacy type value; p (W | P)i) The device is used for judging whether the type characteristics of the ith image data accord with the privacy content judgment coefficient or not and determining a privacy content value; judging whether the content is the private content or not through the sum of the types of the content and the privacy; only in the case of both or only one match, but the sum must be greater than 1, otherwise neither is privacy worthy. i ∈ n, n representing the number of private data.
Step 2, content matching is carried out, and a privacy consciousness value is calculated:
Figure BDA0003515898960000141
wherein, X represents a correlation coefficient, and when X is 1, f (j) represents an image feature of the privacy image of the jth privacy class, which belongs to an image feature trained in advance for comparison.
When the technical scheme is put and the privacy consciousness is worth, a matching algorithm is carried out, then the technical scheme that the image characteristics of the privacy image are obtained through calculation of the matching algorithm and different levels of history is different, when the two are different, the correlation value is judged based on the inertia formula, the corresponding privacy consciousness value is determined according to the correlation value, and the user is more cautious when sending the image through the privacy consciousness value.

The maximum value among the threshold values is the optimal model parameter;
a model library unit: and the deep learning model library is used for generating deep learning according to the optimal parameters of the model.
The principle of the technical scheme is as follows:
according to the invention, a plurality of different deep learning model libraries are required to be arranged, and the model libraries can not only judge the privacy grade, but also continuously optimize the identification of the privacy data in an iterative calculation manner, so that the most appropriate privacy data can be obtained as far as possible. At present, various privacy security threats may be brought by image sharing of a user in a social network, but an effective decision support tool cannot be provided by an existing social network application system, and many defects exist in the aspect of privacy decision aiming at image sharing of the social network in the existing theoretical model and method research. Aiming at the application requirements and the current situation of theoretical research, the invention comprehensively operates methods and means such as human-computer interaction, deep learning, differential privacy and the like, researches and designs a privacy decision model in network image sharing, explores and solves related scientific problems, and the lung and innovates the content and the method of multimedia information security research, thereby providing core algorithm and technical support for the privacy security application of social network image tray information. Therefore, the invention establishes a plurality of different deep learning models. At the present stage, some disadvantages exist, such as that most of the methods are based on manual marking, not based on automatic recognition of image semantics, so that the burden of users is increased, and many users are unwilling or even unable to perform manual labeling, so that the method is ineffective. If the user cannot complete effective manual marking under the drunk condition, part of old people or teenagers cannot complete accurate marking. Meanwhile, the privacy level analysis can be performed by using the image information, such as "the more people in the image, the higher the privacy level", and "the brighter the image, the lower the privacy level", but these rules have no universality.
Based on the consideration, the social network image privacy decision model is constructed by adopting the current rapidly developed deep learning technology, and the more accurate and effective privacy decision model is designed by utilizing the advantages of the deep learning technology in the aspects of image privacy semantic understanding and matching, so that the trouble of the problems is solved.
