Magento

hello every one, Im a student and at the moment im working with my thesis, in my thesis I must make clear the questions: What do you think about the trends of security in eCommerce? I hope anyone can give me help, thank you very much.

I think you should read about PA-DSS standards:

https://www.pcisecuritystandards.org/security_standards/documents.php?association=PA-DSS

It is one of the latest VISA requirements.

Also, this is quite interesting (about mobile/ecommerce payments): http://corporate.visa.com/media-center/press-releases/press1142.jsp
