Globally, Blockchain could help with reliability, security, transparency and could be a consistent step toward reproducibility. In the future, the complex data flow of a clinical trial could be tracked by using Blockchain, which core functionality, named Smart Contract, could help prevent clinical trial events not occurring in the correct chronological order, for example including patients before they consented or analysing case report form data before freezing the database. However, in a live clinical trial, the authentication system should be strengthened to remove the need for third parties, here trial stakeholders, and give participative control to the peer users. It should be considered a robust proof of data. This document cannot be corrupted and can be checked on any dedicated public website. We obtained a single document, in an open format, that accounted for the whole consent collection process: a time-stamped consent status regarding each version of the protocol. For each protocol revision, consent was sought again. ![]() We designed a Proof-of-Concept protocol consisting of time-stamping each step of the patient’s consent collection using Blockchain, thus archiving and historicising the consent through cryptographic validation in a securely unfalsifiable and transparent way. From a more general and prospective point of view, we believe Blockchain technology brings a paradigmatical shift to the entire clinical research field. This is a distributed technology that brings a built-in layer of transparency and traceability. For that, we build a consent workflow using a trending technology called Blockchain. Our goal is to implement a process allowing for collection of patients’ informed consent, which is bound to protocol revisions, storing and tracking the consent in a secure, unfalsifiable and publicly verifiable way, and enabling the sharing of this information in real time. ![]() ![]() Its recording capabilities include a diverse range of actions, while the filtering options help you group the logged items in different categories.Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders. PC Agent can be of assistance in recording the user activity on your computer, allowing parents to closely supervize their children. Recorded files are encrypted and can be uploaded to a FTP server, saved to a locally stored archive or a shared network folder, but you can also set the program to send them to you via e-mail. PC Agent can also interact with the installed web browsers to log visited web pages and input form data or connect to e-mail clients to gather data on the received and sent messages. Periodically, it takes desktop screenshots and captures images from active webcams, sending them to a dedicated folder for later viewing. Also, it can remember data regarding user logins, including remote connections.Īside from this, it is capable of recording clipboard entries and data concerning the accessed or modified files, printing and scanning tasks, the computer power state history and connected storage media. ![]() It logs keystrokes (Unicode characters and various keyboard layouts are supported) and mouse clicks, also storing the text under the cursor. The range of activities it can record is satisfactory enough to please all demands. To restrict the user access, its configuration window is password-protected. The monitoring service can be installed on the target system, with a custom name and description, so as not to betray its presence in Task Manager or other applications. PC Agent is just one of the many such tools that logs actions that are carried out, without getting caught. Keyloggers are applications that can give you a helping hand in this matter, offering a way to record the user activity while running in hidden mode. If your computer is used by more than one person or by children, you might want to know the operations that they perform, for security reasons.
