Enhanced image encryption with deep generative models using a self-attention mechanism.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Image security in visual data is growing in importance due to the increasing use of digital images in many applications. This paper describes a novel image encrypting system using deep generative models with a self-attention mechanism to improve encrypting speed, decrypting speed, or both. Based on the CycleGAN models, the encrypting generator encrypts images while a dedicated decryption network decrypts them properly. The self-attention module improves the dispersibility of visual data to capture global dependencies among images at variable scales to achieve a highly secure image transformation with high reconstruction accuracy. Performance analysis has been done using two color image sets, brain MRI images to detect brain tumors, and images to detect skin cancer. Analysis indicates high security (Entropy = 7.9996, NPCR ≈ 99.99%), high reconstruction accuracy (SSIM ≈ 0.99, PSNR > 40 dB), and high resistance to differential (UACI ≈ 33.46) and occlusion attacks to images. This paper opens up novel avenues in applying deep models to visual cryptography schemes.
