How to restrict asset downloads on the AEM publish side?

[SRK_1D]

We are building a website on AEM where the website visitors are allowed to download few assets (Such as PDF files, zip files, images etc). However, for certain assets, we have a requirement to capture the user's name and email ID before they could download the asset. Is there a way to implement this restriction on the publish side?

Hi,

Restricting download needs to be handled by javascript and depends on the browser, it is not something AEM can handle. You can create a form to enter user name and email id before allowing user to download.

Hi @sai_rama_krishn ,

You can utilize CUG concept in order to achieve this. see this example - https://experienceleague.adobe.com/docs/experience-manager-learn/assets/advanced/closed-user-groups....

Just this configuration will not help you to achieve this, you will have to write a custom authentication handler. As soon as the user tries to access the restricted asset,  you can show a form popup or redirect and have a form where you will collect the user data, once the data is collected you will redirect the user to access/download the asset. Here is a sample implementation with the code - https://www.linkedin.com/pulse/creating-custom-authentication-handler-aem-cq5-navin-kaushal
