The study addressed a new term, the term "criminal hypothesis bank," which assumes the existence of a repository of criminal behavior. It clarified the nature of this term, analyzed each of its expressions, and highlighted its importance and role in the process of investigating, searching, and investigating crimes. It also highlighted how it can be an effective tool in this field. Furthermore, the novelty of this term can raise the question of who can manage this system, which is what the study demonstrated. It identified systems capable of successfully managing it to ensure optimal success. The research hypothesis is based on the existence of a bank containing previously committed criminal behaviors, which can be used to solve future crimes. It is assumed that this bank is managed by the judicial institution, and then assumed that it is managed by the security institution, with an explanation of the advantages and disadvantages of managing each entity. We divided the study into three sections and concluded it with a conclusion, presenting the findings and recommendations we believe should be directed to the legislator and relevant authorities.
