In threshold secret image sharing schemes (k, n), the secret image S is distributed among n shareholders. To recover the secret image, at least k shareholders must be present during the restoration phase. In the traditional secret image sharing schemes, there is no ability to change the threshold or define a share for essential and non-essential shareholders. In certain circumstances, it may be necessary for certain shareholders to be present during the secret recovery phase and surrender their shares. This requires the use of essential secret sharing schemes. Additionally, if the security policy for the recovery phase changes, the number of shareholders required to be present may change as well, necessitating the use of changeable secret sharing schemes. In this paper, a changeable threshold secret image sharing scheme with the presence of essential shareholders is introduced for the first time. In this scheme, the threshold of essential and non-essential shareholders can be increased or decreased based on the chosen policy. Also, the shares of the shareholders are verified using the Bloom Filter. Tables 7 and 8 outline the advantages and features of the proposed scheme in comparison to other schemes.
