Image-Centric Social Discovery Using Neural Network under Anonymity Constraint
Bibliographic record
Abstract
Image sharing is one of the most attractive features facilitated by different social media sites such as Facebook, Flickr, Pinterest, and Instagram. People frequently use these social media sites to express various aspects of their life with peers they are connected through these sites. The service providers of these sites sometimes use the image features for social discovery such as friend recommendation, group or community recommendation, etc. As images are rich in content and more expressive, it also reveals much sensitive information about a user and impedes their privacy. Due to storage constraints, many popular social media sites prefer to outsource their data to the cloud server. However, if the cloud server gets compromised, then an adversary can use these sensitive images for malicious purposes. In this paper, we propose a privacy-preserving image-centric social discovery framework using the neural network and efficient anonymization scheme based on optimum feature selection. Experimental results show that our proposed approach provides better accuracy than existing method as well as is scalable for big datasets.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
