Abstract

A method, system and software for enforcing execution of executable code in accordance with usage rights, including receiving a request generated by a user computing device to execute the executable code, and determining by a repository included in the user computing device whether the request should be granted based on usage rights associated with the executable code. The usage rights include a manner of use indicating a specific instance of how the executable code can be executed. The executable code is executed on the user computing device in accordance with the manner of use, if it is determined that the request should be granted. The request and the executing are accomplished through an interface. The executable code is executed in an address space of the user computing device. The user computing device is permitted to access the executable code only through the interface.

Claims

1-66. -66. (canceled)

67. A method for enforcing execution of executable code in accordance with usage rights, the method comprising;

receiving a request to execute the executable code;

determining at a repository included in a user computing device, based on usage rights associated with the executable code, whether the request should be granted,

wherein the usage rights include a manner of use indicating a specific instance of how the executable code can be executed; and

executing the executable code on the user computing device in accordance with the manner of use, if the result of the determining step is that the request should be granted,

wherein the request is generated by the user computing device,

the determining step is accomplished by the repository included in the user computing device,

the request and the executing step are accomplished through an interface, and

the executing step includes executing the executable code in an address space of the user computing device, and permitting the user computing device to access the executable code only through the interface.

68. The method as recited in claim 67, wherein the request specifies a manner of use indicating a specific instance of how the executable code is to be executed, and the determining step includes determining whether the manner of use specified in the request corresponds to a manner of use included in the usage rights.

69. The method as recited in claim 67, wherein usage rights and executable code are stored on different devices.

70. The method as recited in claim 67, wherein usage rights and executable code are stored on different storage means.

71. The method as recited in claim 67, wherein the usage rights include at least one condition that must be satisfied to exercise the manner of use.

72. The method as recited in claim 67, wherein the executable code is a database search program for a database, and the executing step includes searching the database.

73. The method as recited in claim 67, wherein the executing step includes executing at least a portion of the executable code on the user computing device, and removing the contents of the executable code from a memory of the user computing device after the executing step.

74. The method as recited in claim 67, wherein the executable code is a software program.

75. The method as recited in claim 67, wherein the executable code is binary code.

76. The method as recited in claim 67, wherein the executable code includes plural distinguishable parts.

77. The method as recited in claim 76, wherein the distinguishable parts are stored in different devices.

78. The method as recited in claim 76, wherein at least some of the distinguishable parts have distinct usage rights associated therewith.

79. The method as recited in claim 67, wherein at least one of executable code and a usage right are stored on a removable storage device.

80. The method as recited in claim 71, wherein at least one of said conditions includes possession of a digital ticket.

81. The method as recited in claim 77, wherein the distinguishable parts are stored on different storage means.

82. The method as recited in claim 67, wherein the method is implemented with a computer system including one or more hardware and/or software components.

83. The method as recited in claim 67, wherein the method is implemented via one or more computer readable instructions embedded on a computer readable medium and configured to cause one or more computer processors to perform the steps of the method.

84. A system for enforcing execution of executable code in accordance with usage rights, the system comprising;

a user computing device configured to generate a request to execute the executable code;

a repository included in a user computing device and configured to determine at based on usage rights associated with the executable code, whether the request should be granted,

wherein the usage rights include a manner of use indicating a specific instance of how the executable code can be executed; and

the user computing device executes the executable code in accordance with the manner of use, if the repository determines that the request should be granted,

the user computing device generates the request and executes the executable code through an interface,

the user computing device executes the executable code in an address space of the user computing device, and

the user computing device is permitted access to the executable code only through the interface.

85. The system as recited in claim 84, wherein the request specifies a manner of use indicating a specific instance of how the executable code is to be executed, and the repository determines whether the manner of use specified in the request corresponds to a manner of use included in the usage rights.

86. The system as recited in claim 84, wherein usage rights and executable code are stored on different devices.

87. The system as recited in claim 84, wherein usage rights and executable code are stored on different storage means.

88. The system as recited in claim 84, wherein the usage rights include at least one condition that must be satisfied to exercise the manner of use.

89. The system as recited in claim 84, wherein the executable code is a database search program for a database, and the user computing device searches the database.

90. The system as recited in claim 84, wherein the user computing device executes at least a portion of the executable code on the user computing device, and the contents of the executable code are removed from a memory of the user computing device after the execution.

91. The system as recited in claim 84, wherein the executable code is a software program.

92. The system as recited in claim 84, wherein the executable code is binary code.

93. The system as recited in claim 84, wherein the executable code includes plural distinguishable parts.

94. The system as recited in claim 93, wherein the distinguishable parts are stored in different devices.

95. The system as recited in claim 93, wherein at least some of the distinguishable parts have distinct usage rights associated therewith.

96. The system as recited in claim 84, wherein at least one of executable code and a usage right are stored on a removable storage device.

97. The system as recited in claim 88, wherein at least one of said conditions includes possession of a digital ticket.

98. The system as recited in claim 93, wherein the distinguishable parts are stored on different storage means.

99. The system as recited in claim 84, wherein the system is implemented with one or more hardware and/or software components.
