Abstract

Disclosed is a method and system for distribution of digital protected content data via a peer-to-peer data network, wherein for each user connected to said peer-to-peer data network a corresponding credit counter is provided for acquiring protected content data from a content provider, wherein said credit counter is increased depending on the amount of protected content data uploaded by said user to said peer-to-peer data network.

Claims

1-69. -69. (canceled)

70. A method for distribution of digital protected content data via a peer-to-peer data network to which a plurality of users is connected, comprising providing for each user connected to said peer-to-peer data network a corresponding credit counter for acquiring protected content data from a content provider, wherein said credit counter is increased depending on the amount of protected content data uploaded by said user to said peer-to-peer data network.

71. The method according to claim 70, wherein said credit counter of a user is decreased by a decrement value depending on the value of protected content data downloaded by said user via said peer-to-peer data network.

72. The method according to claim 70, wherein said protected content data is uploaded by said user after the user has received a request for the content data from another user connected to said peer-to-peer data network.

73. The method according to claim 72, wherein said request for the content data comprises at least provider identification data for identifying the content provider and content search data for identifying the requested content data.

74. The method according to claim 70, wherein the credit counter is increased by the user by means of a purchase transaction performed between the user and the content provider.

75. The method according to claim 70, wherein said credit counter is increased by an increment award value which is assigned to a corresponding protected data comprising a predetermined amount of protected data when said protected data file is uploaded by said user to said peer-to-peer data network.

76. The method according to claim 70, wherein the protected content data is stored as a file on a server of said content provider connected to said peer-to-peer data network for download by another user.

77. The method according to claim 76, wherein for each protected content data file a corresponding metainfo data file describing the protected content data file is stored on said server of said content provider.

78. The method according to claim 77, wherein each protected content data file consists of at least one protected content data sequence.

79. The method according to claim 78, wherein the metainfo data file of a protected content data file comprises file identification data for identifying the protected content data file and a sequence index for each content data sequence of said protected content data file.

80. The method according to claim 79, wherein the metainfo data file further comprises for each content data sequence of said protected content data file a unique fingerprint checksum of said content data sequence.

81. A computer system for distribution of digital protected content data, comprising a peer-to-peer data network to which a plurality of users are connected, wherein for each user a credit counter is provided for acquiring protected content data from a content provider, said credit counter configured to be increased depending on the volume of protected content data uploaded by said user to said peer-to-peer data network.

82. The computer system according to claim 81, wherein each user comprises a computer connected to said peer-to-peer data network via a data communication link.

83. The computer system according to claim 81, wherein the content provider comprises at least one server connected to the peer-to-peer data network via a data communication link.

84. The computer system according to claim 81, wherein said protected content data is formed by digital protected video data.

85. The computer system according to claim 81, wherein said protected content data is formed by digital protected audio data.

86. A computer of a user for exchanging protected content data via a peer-to-peer data network to which a plurality of users is connected, comprising a corresponding credit counter for said user for acquiring protected content data from a content provider, said credit counter configured to be:

decreased depending on the value of protected data downloaded by said computer from said peer-to-peer data network; and

increased depending on the volume of protected content data uploaded by said computer to said peer-to-peer data network.
