Under the complex and severe testing security situation, the authoritativeness and impartiality of the current unified national examinations are facing unprecedented challenges. Self-taught Examination, due to its nature, examinee characteristics and its specialty scale, is facing worse testing security situation with the pressure of organization, the difficulty of collective management, and the serious problems of cheating in tests, such as surrogate exam-takers. Therefore, it is crucial and imperative to bring the technology and measures needed into the management. To be specific, an anti-cheating supervisory system needs to be set up, which not only involves people supervision at the pre- and while-stages of the examination but also involves technology application of a handwriting identification system at the post-stage of the examination. In contrast to other bio-identification systems, the handwriting identification system is characterized by its high collectability and retrievability, its low rejection rate, and low economic input. Thus, it is so far held as the most adaptable technology that can be applied to the management of Self-taught Examination. Meanwhile, what makes it possible for us to prevent and curb the relevant cheating behaviors is that the system is getting mature in theory and technology.%复杂而严峻的考试安全形势使得国家教育统一考试的权威性和公正性受到巨大挑战。自学考试由于考试性质、生源特点、专业规模等原因，使其组织管理工作呈现组考压力相对较大、集体管理难度较大、替考作弊危害更为严重等特殊性，也使其面临的安全形势更为恶劣。因此，在自学考试组考工作中引入相关技术手段，建立考前、考中“人防”与考后“技防”相结合的身份识别与管控体系十分必要。相对于其他生物识别技术而言，笔迹识别技术具有可采集性高、可回溯性高、拒识率低、经济投入低等优势，是目前最适合自学考试特点的身份识别技术，其相关理论与技术的日臻成熟也为防范和震慑自学考试替考作弊行为提供了可靠保障。
