| Abstract |
In this paper, a framework has been designed, which will maintain a blockchain-based database system. The system will be used for keeping citizens daily life data of a whole city. Basically, this data gives support to any incidence inspection team to scrutinize citizens activity in-depth, for any criminal case that needs to be investigated. To perform this forensic work a framework is required which can keep the data confidential and ensures the data will not be tampered by any party related to an investigation (citizen or personnel from forensic organizations). On the other hand, any unauthorized access from any intruder can be restricted. To prevent data tampering, a blockchain-based data structure has been used by our framework to ensure the immutability. This kind of work is not been done in a collective manner, in earlier time mostly blockchain was used with bitcoin. However, it has a huge potential we have applied this in our framework to work with our daily life activity log data. © 2019 IEEE. |
