Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Most of digital signatures require the secret key when signing a message, hover, there does exists a kind of signature scheme which is able to sign by appending new message only, so-called Append-Only Signature (AOS) [9]. Motivated by its numerous useful applications in network security such as secure routing, etc., in this paper,  propose new efficient AOS scheme with shorter public key (parameters) using ID-based cryptographic techniques. To our surprise, it is the first time to achieve a practical, adaptively secure AOS via ID-based encryption approach. The proposed signature enjoys the merit of security against adaptive attack, while the previously presented AOS is only secure in a ak sense of selective unforgeability. Finally,  also present a new Restricted AOS (RAOS) signature, which may be of independent interest in practice.
