3. From the backup list, select the notarized backup which contains the file that you want to verify.
4. On the right panel, open the Recovery tab.
5. Browse to the required file, click the Menu icon ( ), and then click one of the following:
View certificate—The certificate containing the detailed information about the file
security will be opened in the web browser.
Verify—Acronis True Image 2021 will check the file authenticity.
To verify a file's authenticity by using the File verification tool:
1. Open the File verification tool with one of the following methods:
In a web browser, open https://notary.acronis.com/verify.
On the sidebar of Acronis True Image 2021, click Backup, select a notarized backup, and then
click Open File verification tool on the right panel.
2. In File Explorer, browse to the file that you want to verify, and then drag it to the web browser
window.
If a notarized backup is stored on Acronis Cloud, you can also verify a backed-up file's authenticity in
the Acronis Cloud web application.
To verify a file's authenticity on Acronis Cloud:
1. Go to https://www.acronis.com/my/online-backup/webrestore/, and then log in to your Acronis
account.
2. Browse to the required file, click on the file name, and then click the Verify or Get certificate on
the side bar. See the commands description above.
4.2.1.3 Manual verification of a file's authenticity
The easiest way to verify a file's authenticity is to use the Verify command in Acronis True Image
2021 or in the Acronis Cloud web application. Refer to Verifying file authenticity (p. 50) for details. In
addition to this easy method, you can perform the verification procedure yourself, step by step.
To verify a file's authenticity manually:
Step 1. Calculate MD5 hash of the file
1. Start Windows PowerShell.
2. For example, to calculate the md5 hash for the picture.png file located in C:\Users\picture.png,
type:
$($(CertUtil -hashfile "C:\Users\picture.png" MD5)[1] -replace " ","")
Example of an md5 hash: eea16ade1edf2750a46bb6bffb2e45a2
3. Check that the calculated md5 hash is equal to an eTag in the DATA field in your notarization
certificate. Refer to Verifying file authenticity (p. 50) for details about obtaining a file certificate.
Step 2. Check that a ROOT is stored in the blockchain
1. Open a blockchain explorer, for example https://etherscan.io/.
2. Enter the TRANSACTION ID from the certificate into the search field.
3. Check that the Data field in the Event Logs tab is equal to the ROOT value in your certificate.
