The company said it does not share user information.
After Adobe was criticised for allegedly sending user data to servers from Adobe Digital Editions 4 without encryption, the company is rolling out a software update which will encrypt the data it collects about certain ebooks.
Adobe’s Digital Editions 4 software sends details of the ebooks accessed by the user which includes user GUID, device GUID, percentage of the ebook read and duration for which the book was read to its servers without encryption.
Reports suggest that the unencrypted data was vulnerable to cyber attack and snooping which could eventually reveal user information.
With the latest software update the company is encrypting the information using HTTPS, only if the book contains copy-protection measures.
The copy-protection measures or the digital rights management (DRM) is used by eBook providers to manage printing, sharing copying of eBooks
The company said in its blog that it now periodically collects the data "using HTTPS.", and the change has been made in Digital Editions versions 4.0.1 for Mac and Windows.
In its blog Adobe said: "Adobe does not share any personally identifiable information.
"Adobe may share anonymous aggregated information with eBook providers to enable billing under the applicable pricing model."
