1 Recurrent allegations of electronic question paper (e-QP) leakage and examination malpractices in educational institutions can be handled by the course faculty (F) securely transferring e-QP data to a trustworthy collector (C). In this case, is mix run length encoding (RLE) for binarized diagrams tamper-resistant text encrypted with modification technique. QR codes are being utilised encode combination two halves secret data. Digital watermarking used embed code chunk same second. Its n image shares generated F through deterministic XOR based (n, n)-Visual Cryptography (VC). These submitted non-trusted parties which deliver their respective portions C before examination. performs all necessary operations get back full its raw form. The resulting RLE plaintext format decompress pictures e-QP. This paper, therefore, suggests explores usage VC construction secure cryptosystem that robust towards ordinary other attacks.
