###### Abstract
One of the most promising and secure approaches to solve these issues is secure searchable encryption (SSE), which enables the users to encrypt the data on their own side without the involvement of a third party. Secure searchable encryption can be divided into two groups named Asymmetric SSE and Symmetric SSE [4]. Our proposed extended secure searchable encryption (ESSE) is based on the motivation from [5]. The authors proposed the idea of Obvious cross Tag (OXT) searchable mechanism. The idea of OXT is to distribute all master keys among the users in order to take more advantages of the protocol. The problem with OXT is the key loss or collusion attack, which make it more prone to vulnerabilities. Our proposed approach is more resilient to active collusion attack and key loss situations. Moreover, our proposed method is flexible enough to be applied to different platform such as social media, fog computing, and other IoT-based applications [6]. In this research paper we have proposed extended multi-user-extended SSE which support the participants to query securely against desired keyword search in the distributed ledger. The patient encrypts the data at the beginning and uploads it to the blockchain. Our research method provides facility to the data owner once the data owner completed the encryption, it will not be necessary to be involved in other processes until he or she needs policy revocation or deletion. As known for its flexibility and accessibility, cloud computing is a multi-functional platform for data storage. However, data outsourced to the cloud might be considered insecure because the data owner's control over the data is limited, which potentially poses more security issues. Similarly, security issues become the primary concern when it comes to the healthcare industry. Most of the current healthcare data and patient records are stored in the cloud, thus, dealing with medical records is a concern which is widely shared. Digital health records including sensitive patient data are seen as some of the most valuable data, however, it is also vulnerable due to the cloud-based platform, which gives the unethical third parties more chances to access or steal the data due to the market value [7]. Althoughadvancement has been made in access control schemes and frameworks, however, issues still exist in the proposed schemes. These include the absence of measuring granularity in authorizing [8], reliance on identity, and role or purpose-based access control schemes [9]. The existing access control system only relies on identity, or role-based and attribute-based methods. Through a series of comparative analysis, it has been observed that the most appropriate access control strategy among the existing solutions is ABE [10]. The Public-Key encryption does not overcome the security aspects of the attribute-based encryption. Consequently, in the proposed solution, we have used Attribute Based Signature (ABS), since it guarantees anonymity as well as unforgeability to the signer [11; 12]. The aim of our proposed strategy is to secure the Personal Health Record (PHR) leveraging homomorphic encryption and fine-grained access control without any security loss or threat. To achieve our goals, we propose a novel protocol based on data sharing via combining two latest attribute based cryptography schemes and homomorphic encryption with an ABAC model using hyperledger fabric. Furthermore, we have provided a detailed comparison based evaluation of our scheme with several state-of-the-art schemes. The critical difference of the proposed scheme and the traditional the application of the computational trust-based value. The advantages of trust evaluation includes:  
1. Developing a novel lightweight consensus mechanism by combining with the BFT protocol;
2. Measuring the trustworthiness of the user and presumers before creating smart contracts and before initiating interactions among several parties;
3. Moreover, it also helps in the accountability of the privacy and consent violation;
4.
