A desensitization management intelligent chip and method for rehabilitation follow-up data
By collecting user opinions and status data to assess privacy protection thresholds, segmenting data dimensions by features, evaluating value based on predictive models, and finding the optimal desensitization scheme, this approach solves the problems of unified rules, dynamic assessment of privacy protection thresholds, and neglect of data utility in the management of desensitization of rehabilitation follow-up data, achieving a balance between personalized privacy protection and data utility.

AI Technical Summary
Existing desensitization management techniques for rehabilitation follow-up data have several problems, including: over-desensitization of high-value data due to uniform rule processing; lack of dynamic assessment of privacy protection thresholds; neglect of the actual utility of data in incremental model learning; and lack of optimization and seeking mechanisms in the generation of desensitization schemes.
The system employs a data collection and threshold assessment module to acquire user subjective opinions and objective status data, and uses an expert system to assess the privacy protection threshold value; a feature segmentation module divides the data into multiple dimensions; a value assessment module evaluates the value of data dimensions based on a predictive model library; and a strategy optimization module uses the privacy protection threshold as a constraint to find the optimal de-identification scheme that maximizes data utility and privacy protection performance.
It enables personalized and dynamic adjustments to privacy protection needs, refined quantification of data utility, and full release of data analysis value under the premise of privacy and security, providing an intelligent de-identification management solution for rehabilitation follow-up data.
