US online retail giant Amazon is planning to launch a "cloud" service for storing videos and music online, enabling individuals to access their files from a range of digital devices, the Wall Street Journal said.
The Seattle, Washington-based Amazon may announce the project as early as Tuesday, said the financial daily, citing sources close to the matter.
However the company is still ironing out key legal issues related to the service, the sources said, including being yet to secure content licenses from some major record labels and movie studios.
"We are disappointed that the locker service that Amazon is proposing is unlicensed by Sony Music," a spokeswoman for Sony Corp.'s Sony Music Entertainment told the Journal.
The online store appears to be jumping into an online field where rivals Apple and Google are already working on similar "cloud" computing projects for online file collections a user could access from a variety of computers or other devices.
