“…On the other hand, if the concepts were connected by writing characters or numbers listed in front of the given answers, a convolutional neural network could be of use [2,3,30]. However, a real challenge would be to detect handwritten essays in open-text type questions and interpret text meaning, which would require the usage of deep neural network models [14,15] and natural language processing techniques [5]. Furthermore, if the software could someday verify the integrity of the text handwritten by the pen [8,24], that would significantly contribute to preserving the examination process's soundness.…”

“…Recently, a text-based CAPTCHA technique based on the Hindi language that concurrently uses printed and handwritten Hindi characters is presented [39]. In this work, k-nearest neighbours, support vector machines, and random forest classifiers are used to break ten distinct coloured CAPTCHAs.…”

“…Few recent schemes has applied denoising for breaking the text-CAPTCHAs [39]. Likewise, we have tested several types of noise added to the SMC to offer an extra layer of security, shown in Fig.…”

“…Ref. [33] introduced a novel CAPTCHA design incorporating the Hindi language, combining printed and handwritten characters to bolster security. Its distinctiveness is evident in its quest for a CAPTCHA with a "sweet spot" feature, harmonizing user-friendliness and machine-resistant characteristics.…”
