IT Crime
Multimedia messaging service (MMS) via mobile phones is a recent development which is slowly replacing short message service (SMS). The system aims at not only the exchange of messages between mobile phones but also between mobile phones and e-mail (and vice versa). The content is not limited to text; it also comprises sound, images and other rich content. In other words, MMS enriches communication with ‘real and live content’. Images or audio or video files are not attachments but appear within the body of the message as multimedia content. In the case of pictures, sound and video such as JPEG, GIF or MP3, these files will most probably be compatible with any PC equipped with commonly available software, including Microsoft Office. Unless the files are too large, transmission is simple and does not dramatically burden the network, as it is transmitted the same way as an SMS. This system may even be able to handle short PowerPoint presentations. Estimates from Nokia suggest that there will be enormous growth of SMS traffic in the coming years due to the advent of MMS, although at the moment compatible mobile phones are not numerous enough or widely used enough to have a significant impact. For mobile phones without MMS capabilities, phone companies might provide users with an additional service which delivers an SMS to the recipient indicating where the MMS is stored and where it can be accessed on an Internet site. Additionally, for users without mobile phones with digital cameras or audio software installed, many optional accessories at affordable prices which can be plugged into the phone are available. Finally, another technical solution may be installing e-mail gateway software in the phone in order to send an MMS directly to a recipient by e-mail.
The criminal risks related to the use of MMS are quite clear. The possibility of exchanging files in diverse forms represents a real threat to society if the content is illegal. It is easy to see how child sexual abuse images could be transmitted this way. The criminal use of this system could be very wide, e.g. the spread of viruses. The main problem for law enforcement is the ease with which criminals could use the technology to upload, download and disseminate files with illegal content. Another risk is anonymity: criminals can use virtually untraceable pre-paid cards for moving files and then discard them immediately after use. Finally, the use of smart phones (as explained above) equipped with cameras may be an additional tool for criminals to disseminate illegal material.
