Authenticating health activity data using distributed ledger technologies

The review suggests that management of access control has seen extensive investigation.

“The review suggests that management of access control (Zheng et al., 2019) has especially seen extensive investigation (Badr et al., 2018;Brogan et al., 2018).”

Prior studies addressed authentic data mobilization, avoidance of data leakage or double spending on storage, and perpetual data preservation.

“For instance, prior studies have addressed issues pertaining to authentic data mobilization (Brogan et al., 2018), avoidance of data leakage (Zhang et al., 2016;Zhou et al., 2018) or double spending on storage (Rahmadika & Rhee, 2019), and perpetual data preservation (H.Li et al., 2018).”

A few studies reported algorithm-specific constraints including lack of mature scheme for PSN-based blockchains and lack of optimized MAM module library.

“A few studies have reported constraints specific to their developed algorithms, such as a lack of a mature scheme for PSNbased blockchains for healthcare (Zhang et al., 2016), and a lack of an optimized masked authenticated messaging (MAM) module library (Brogan et al., 2018).”

Concerns may relate to users' management/mismanagement of authorized private keys.

“Such concerns may also be related to maintaining the security of the proposed frameworks from the users' perspectives, for example, the users' management or mismanagement of their authorized private keys (Brogan et al., 2018).”

In the reviewed literature, relatively less attention has been paid to the prevention of external attacks, such as attacks on sensor data, escrow, and collusion attacks.

“However, relatively less attention has been paid to the prevention of external attacks, such as attacks on sensor data (Brogan et al., 2018), escrow, and collusion attacks (Guo et al., 2018).”
