Despite the use of passwords to protect computations, bank robbery has increased by the end of the twentieth century. This occurs when one of the bank employees passes the password to embezzlers. This matter has led to finding a secret sharing scheme to improve the security and secrecy degree; this scheme uses a number of participants, and each participant obtains a part of the secret information, whereupon none of the participants can unilaterally divulge this information. The research studies the secrecy degree of the Secret Sharing Schemes. Finally, we have highlighted the following: 1- The secret sharing schemes for uniform access structures is the best. 2- A scheme to improve the security and protection of secret information. 3- The relationship between the access structure degree and the number of participants in each secret sharing sub-group
