# Data ingestion: Transfer and Integrity
* When sending data: <font color="red">Do not use emails, use secure platforms (Cloud, Aspera, Atlas share...)!</font>
<div class="fragment">
Data can be corrupted:
* (non-)malicious modification
* faulty file transfer
* disk corruption
</div>
<div class="fragment">
### Solution
* disable write access to the source data
* generate checksums!

<img src="slides/img/checksum.png" width="500px">
</div>
</div>
<div class="fragment" style="position:relative; left:0%">
## When to generate checksums?
* before data transfer
- new dataset from collaborator
- upload to remote repository
* long term storage
- master version of dataset
- snapshot of data for publication
