A method and apparatus for enabling a licensed end user to record digital data as described is particularly useful to the music industry as it enables them to make audio data available over the internet but to retain control of the uses to which that audio data can be put. Thus, upon completing a financial transaction to pay for the required audio tracks, the end user is enabled to download and decrypt encrypted music tracks and to play them on the end user's personal computer. The end user can also be allowed to burn a CD including the downloaded music tracks. However, the end user is only enabled to decrypt and record the music tracks onto the CD if the music tracks are recorded together with copy protection.
A method of enabling a licensed end user to record digital data, the method comprising the steps of providing, at the request of a licensed end user, digital data in encrypted form, and enabling the licensed end user to record the decrypted digital data onto a data carrier, the method further comprising the step of requiring that the decrypted digital data can only be recorded onto the data carrier together with means which provide copy protection for the decrypted digital data.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein the method comprises the step of licensing the end user upon completion of a financial transaction between the end user and a supplier of digital data to record the decrypted data, in copy protected form, onto a number of data carriers.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein the means recorded onto the data carrier to provide copy protection for the decrypted digital data comprises a digital signature and a verification routine requiring access to the digital signature.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein to record means onto the data carrier to provide copy protection for the decrypted digital data, the method comprises encoding incorrect and/or inaccurate control data onto the data carrier, the control data which is incorrect and/or inaccurate being usuable by a reader of the digital data.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein to record means onto the data carrier to provide copy protection for the decrypted digital data, the method comprises altering format and/or control data provided on the recordable data carrier.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein the digital data to be recorded has been downloaded by way of the internet.
A method of enabling a licensed end user to record digital data as claimed in any preceding claim, wherein the digital data is audio data, video, images and/or application files and the data carrier is an optical disc such as a CD or a DVD.
A method of enabling a licensed end user to obtain and record digital data as claimed in any preceding claim, the method further comprising providing digital data required by the end user after encryption of the digital data using a key generated by and stored by the end user, completing a financial transaction between the end user and the supplier of the digital data to licence the end user to obtain the digital data, and indicating the completion of the financial transaction whereby the end user is enabled to obtain and decrypt the encrypted digital data utilising the key stored by the end user.
Apparatus for enabling a licensed end user to record digital data, said apparatus comprising processing means arranged to receive digital data in encrypted form and to decrypt the received digital data, and recording means for recording the decrypted digital data onto a data carrier, the apparatus further comprising means constraining the recording means to record the decrypted digital data onto a data carrier together with means protecting the digital data against copying.
An executable application file arranged to cause an end user device to record digital data onto a data carrier, the application file comprising:
A method of enabling a licensed end user to record digital data, the method comprising the steps of:
Apparatus for enabling a licensed end user to record selected digital data, said apparatus comprising processing means arranged to communicate with a financial server whereby a financial transaction can be completed to obtain for the end user rights over selected digital data, the processing means being arranged upon completion of the financial transaction to obtain the selected digital data and to use the selected digital data in accordance with the licensed rights, and the apparatus further comprising recording means for recording the selected digital data onto a data carrier, wherein the selected digital data is made available in encrypted form and the processing means is enabled to decrypt the selected digital data for licensed use and for licensed recording.
An executable application file arranged to enable an end user device to record digital data onto a data carrier, the application file comprising:
