DETAILED DESCRIPTION

For enhancing file transmission between a personal computer and a portable electronic device, the present invention discloses some file transmission methods. In a first embodiment of the present invention, the disclosed file transmission method is utilized for enhancing anonymous file transmission, and in a second embodiment of the present invention, the disclosed file transmission method is utilized for enhancing file transmission under a same identity.

Please refer toFIG. 1.FIG. 1shows file transmission structure100according to a first embodiment of the present invention. The disclosed file transmission structure100comprises a personal computer110, a server120and a portable electronic device130. The operation of the disclosed first embodiment of the present invention is supported by a file transmission program NT. The file transmission program NT is installed and run in the server120and the portable electronic device130in advance so that the following described operations related toFIG. 1are supported. It is assumed that the user of the portable electronic device130has the intention of downloading a plurality of files from the personal computer110. It is further assumed that the user has the intention to download the plurality of files anonymously to the portable electronic device130.

The personal computer110shall upload the plurality of files to the server120through a web based accessing site. After the server120has received the plurality of files, it will generate an image code and a thumbnail. The image code is utilized for downloading the thumbnail and the thumbnail corresponds to a category of the plurality of files. The image code shall be transmitted to the personal computer110and displayed through the web based accessing site. The encoding scheme used to generate the image code may be a QR code and/or a watermark code. The user shall use the portable electronic device130to scan and decode the image code and identify and download the thumbnail. The file transmission program NT is capable of using a decoding scheme corresponding to the encoding scheme. The portable electronic device130shall download the thumbnail from the server120. The thumbnail is displayed on the portable electronic device130to show the category of the plurality of files. The user may give a command through the thumbnail and send the command to the server120using the file transmission program NT for downloading at least one of the plurality of files from the server120to the portable electronic device130.

As can be observed in the abovementioned descriptions related toFIG. 1, the mechanism shown inFIG. 1does not require any registration of identities to the file transmission program NT run on the server120and the portable electronic device130. The mechanism is performed in an anonymous manner so that it relieves the burden of registering a required identity to the file transmission program NT for accessing files on the personal computer110, and file transfer from the personal computer110to the portable electronic device130is more convenient as a result.

Please refer toFIG. 2.FIG. 2shows a file transmission structure200according to the second embodiment of the present invention. Instead of utilizing an anonymous mechanism, the mechanism shown inFIG. 2is performed by using a same identity that is registered to the file transmission program NT via the server120. The same identity is simultaneously shared and used by the personal computer110and the portable electronic device130. Similar withFIG. 1, the file transmission program NT is also run on the server120and the portable electronic device130in advance so that the following described operations related toFIG. 2are supported.

First, the personal computer110shall upload a plurality of files onto the server120under the same identity through a web based accessing site. Second, the portable electronic device130is configured to download at least one of the plurality of files from the server120under the same identity as the personal computer110.

Similarly as mentioned in the first embodiment of the present invention, a thumbnail is also generated to correspond to a category of the plurality of files by the server120and that the portable electronic device130is capable of displaying the thumbnail on the portable electronic device130using the file transmission program NT. The user may give a command through the thumbnail and send the command to the server120using the file transmission program NT for downloading at least one of the plurality of files from the server120to the portable electronic device130.

The mechanism shown inFIG. 2fulfills security requirements since the file transfer from the personal computer110to the portable electronic device130is performed under the same identity.
