<h2>Security considerations</h2>
<p>
Provenance is central to establishing trust in data. If provenance information is corrupted, it may lead agents (human or software) to draw inappropriate and possibly harmful conclusions. Therefore, care is needed to ensure that the integrity of provenance information is maintained. Just as provenance information can help determine a level of trust in some information, provenance information related to the provenance itself ("provenance of provenance") can help determine trust in the provenance itself.
@@ -800,8 +709,6 @@
</p>
<p>Provenance information may be used by audits to establish accountability for information use [[INFO-ACC]] and to verify use of proper processes in information processing activities. Thus, provenance management systems can provide mechanisms to support auditing and enforcement of information handling policies. In such cases, provenance information itself may be a valuable target for attack by malicious agents, and care must be taken to ensure it is stored securely and in a fashion that resists attempts to tamper with it.
