data integrity

A dimension of data contributing to trustworthiness and pertaining to the systems and processes for data capture, correction, maintenance, transmission and retention. In clinical research, the FDA requires trustworthiness of data relied on to determine safety and efficacy of therapeutic interventions, and establishes guidance and regulations concerning practices and system requirements needed to promote an acceptable level of data integrity.

Key elements
Security, privacy, access controls, a continuous trail from capture to archive, stability (of values and attribution), protection against loss or destruction, ease of review by users responsible for data quality, proper operation, validation of systems, training of users.

Sensitivity is the second property of message integrity. Sensitivity is a measure of the confidentiality of the information exchanged.
As noted, personal relationships were found to enhance communication processes along four distinct constructs: message integrity, message conveyance, environmental interaction and communication performance.
Specifically, it was found that personal relationships (1) enhance the message integrity by increasing the honesty of the message transmitted and facilitating the exchange of sensitive information, (2) enhance the message conveyance process by increasing the ease of communication, the ease of contact, the accuracy of interpretation, and the frequency of communication, and by adding new channels and levels of communication, (3) enhance the environmental interaction by reducing tension when communicating and allowing for uncensored communication, and (4) enhance communication performance by increasing communication efficiency and increasing communication effectiveness.
Three types of PEM messages are defined to provide different combinations of security services for different messaging contexts: MIC-CLEAR, MIC-ONLY, and ENCRYPTED.(4) A MIC-CLEAR message employs a cryptographic message integrity code (MIC) to check the integrity and authenticity of the message, but no confidentiality is provided and the encoding step is omitted to permit viewing by recipients who have not implemented PEM.
Submission processing in PEM involves three major transformation steps: canonicalization, computation of the message integrity code (MIC) and optional message encryption, followed by optional 6-bit encoding.
The second step in PEM message processing begins with the calculation of the message integrity code (MIC).
When compared to CTR mode, SPCBC provides message integrity and chain dependency that may lead to an error propagation of one block.
The software incorporates an electronic shopping cart, allowing certificates and digital signatures to verify the identity of parties in information exchanges and transactions; and message integrity, which ensures that messages cannot be altered en route.
