歩骤 306. CIM将内容以及 CONTENT— ID所对应的随机数更新为本次申 请中的注册请求消息中解密出的随机数 RAND,将内容以及 CONTENT— ID对 对应的时间戳更新为本次申请的注册请求消息中的时间戳。在本发明的另一 个实施例中, CIM还可以将相似或相同内容所对应的内容所有者的信息更改 为本次申请的内容的所有者, 可以是将内容所有者信息更新为上述内容属性 描述 Attri— Data。 以上更新进一歩可以是对歩骤 303中描述的注册记录进行操 作。
歩骤 206.内容 ID管理服务器向内容所有者终端返回注册响应信息, 所述 注册响应信息包含对所述内容注册成功或注册失败的信息。
通过上述的过程实现了内容所有者通过终端对内容的注册, 内容的所有 者可以通过其终端在歩骤 201中所生成的随机数 RAND证明其对相关内容的 所有权, CIM中的时间戳表明了与其相对应的内容的出现时间。
本发明实施例提供的一种由内容的受让者发起的内容所有权变更的处 理方法的流程, 如图 4所示, 其中, COT (Content Owner Terminal) 为内容 所有者终端, 内容的所有者将通过 COT与内容 ID管理服务器 CIM以及内容受 让者终端 CPT(Content Purchaser Terminal)进行信息交互, 以实现内容所有权 的变更; CPT为内容受让者终端, 内容受让者将通过 CPT与 COT,CIM进行信 息交互实现内容所有权的变更。 在此之前, 内容的所有者已经在 CIM上进行 对其所有内容的注册。 所有权变更的具体流程如下:
歩骤 401.内容受让者终端 CPT向内容所有者终端 COT发送受让请求消 息, 该受让请求消息中包含所有权置换随机数或加密隐藏后的所有权置换随 机数,以及需要受让的内容,该内容在受让前属于 COT所对应的内容所有者, 也可以包含需要受让的内容的标识, 例如是在 CIM中存储的 CONTENT— ID。 受让请求消息中还可以包含内容受让者信息 CP— IDmfo, 例如受让者身份的 标识可以是受让者的姓名, 组织名, ID等。 受让者终端可以将内容受让者信 息 CP— Idinfo , 以及受让者终端 CPT生成上述随机数 RAND2组合形成串连信 息,并计算此串联信息的散列运算值得到 Hash CP— Idmfo+ RAND2;>,进一歩根 据所需要受让内容标识 CONTENT— ID, 内容受让者信息 CP— Idinfo, 需要受 让的内容, 以及上述 Hash CP— Idinfo+ RAND2)生成受让请求消息。 也可以直 接计算 Hash(RAND2), 根据 Hash(RAND2), 以及需要受让的内容生成受让请 求消息。
歩骤 402.内容所有者的终端 COT 根据所述受让请求消息中的内容或内 容标识,判断该内容或该内容标识所对应的内容的所有者是否为自身,若是, 则进入歩骤 403处理, 若该内容或该 CONTENT— ID所对应的内容的所有者不 是自身, 则不进行后续的处理。
歩骤 403.COT进一歩生成受让请求响应消息, 该信息中包含所有权变更 凭据, 所有权变更凭据根据所述所有权置换随机数, 以及随机数以约定的生 成方式生成。该所有权变更凭据表明内容所有者愿意将内容转让给内容的受 让者, 该随机数为内容的所有者在 CIM中进行对本次要变更所有权的内容注 册时所生成的随机数, 该随机数被内容所有者保存, 用于证明其对内容的所 有。所有权变更凭据的生成方式可以由在每次进行所有权变更时内容的所有 者和 CIM进行约定, 以便 CIM可以对所有权变更凭据进行验证。 上述的约定 也可以是一种统一的方式生成不需要在每次进行所有权变更时进行确认, CIM用该统一的方式对所有权变更凭据进行验证。 所有权变更凭据也可以由 CPT生成, 当所有权变更凭据由 CPT生成时, COT需要向 CPT提供相关信息。 本发明实施例提供一种所有权变更凭据的生成方式, 如下,将上述 CP— Idmfo 以及需要受让的内容或内容标识, 还有内容所有者信息生成转让信息 Excgjnfo , 并进一歩和随机数以及上述歩骤 401受让请求消息中的 Hash(CP_Idmfo+ RAND2)组合形成串联信息,并计算此串联信息的散列运算 值 Hash(Excg— Info+ RAND+ Hash(CP_Idinfo+ RAND2)) , 用该离散运算值做 为所有权变更凭据。 其他所有权变更凭据的方式也是可以的, 例如, 计算 Hash(RAND+ Hash(RAND2)) , 其中 RAND为随机数, RAND2为内容置换随 机数 。 用 该 离散运算值做为 所有权变更凭据 , 或计算 Hash(Hash(RAND)+Hash(RAND2)) 用该离散运算值做为所有权变更凭据。 受让请求响应消息中还可以进一歩包含需要受让的内容或内容标识, COT进 一歩将受让请求响应消息发送给 CPT。
歩骤 404.CPT根据接收到的受让请求响应消息, 生成所有权变更请求, 该所有权变更请求用于向 CIM表明对特定内容的所有权的变更, 该信息中包 含了内容或内容标识, 上述所有权变更凭据, 以及所有权置换随机数。 所有 权变更请求中还可以包含其他信息, 例如内容所有者的信息, 内容受让者信 息等等, 内容所有者信息, 内容受让者信息, 以及内容或内容标识还可以以 转让信息的方式包含在所有权变更请求中, 以上信息进一歩可以加密后包含 在所有权变更请求中传送, 这样防止信息在传输过程中被截获而产生的安全 性问题。所有权变更请求可以用如下方法生成, 将受让请求响应消息中的所 有权变更凭据 Hash (Excg_Info+ RAND+Hash(CP— Idinfo+RAND2》与加密后 的所有权置换随机数 EncRAND2组合形成串连信息, 根据需要受让的内容或 内容标识, 以及上述 EncRAND2+ Hash(Excg_Info+ RAND+ Hash(CP_Idinfo+ RAND2X)生成所有权变更请求。 CPT进一歩将所述所有权变更请求发送到内 容 ID管理服务器 CIM, 请求其处理对相应内容所有权的变更。
歩骤 405.CIM在收到所有权变更请求后, 进行所有权变更的处理。 具体 包括 CIM从所有权变更请求中提取需要进行所有权变更的内容或内容标识, 以及所有权置换随机数 RAND2。 根据内容或内容标识找到注册记录中与其 相对应的随机数,用约定的所有权变更凭据的生成方式验证所有权变更请求 中的所有权变更凭据。 对应与歩骤 203中所介绍一种所有权变更凭据的生成 方式 Hash(Excg_Info+ RAND+ Hash(CP_Idinfo+ RAND2)), 本实施例提供一 种具体的验证方法, 从所有权变更请求中获取内容受让者信息 CP— Idmfo, 并 计算散列运算值 1 Hash(CP— Idinfo+ RAND2)其中 RAND2为所有权变更请求 中所包含的所有权置换随机数, 从所有权变更请求中提取内容或内容标识, 内容所有者信息, 内容受让者信息, 根据以上信息生成转让信息 Excg— Info, 进一歩计算散列运算值 2Hash(Excg— Info+ RAND+ Hash(CP_Idinfo+ RAND2)), 其中 RAND为注册记录中与需要变更所有权的内容相对应的随机 数。若上述得到的散列运算值 2和所有权变更请求中的所有权变更凭据一致, 则验证通过, 以上验证的实质是通过所有权变更请求中的信息结合 CIM自身 注册记录中的信息重新按所有权变更凭据的生成方式构造所有权变更凭据 用来和所有权变更请求中的所有权变更凭据进行比较。 CIM进一歩将注册记 录中的随机数更新为所有权置换随机数,还可以将注册记录中的内容属性描 述 Attri— Data更新为内容受让者信息 CP— Idinfo。 这样内容的受让者可以根据 所有权置换随机数 RAND2证明其对相应内容的所有权, 从而完成了内容所 有权的变更。 此外该歩骤中, CIM可以进一歩根据与此次所有权变更的相关信息, 可 以是根据所有权变更凭据和 /或所有权置换随机数从 DTS服务器获取时间戳, 该时间戳表明了此次所有权变更的时间。 例如, CIM对 Content— ID和 RAND2 组成信息的散列运算值进行签名, 该签名可以用 SignCIM Hash
(Content_ID+RAND2))表示, CIM进一歩用上述
Hash(Hash(Excg_Info+RAND)+Hash(CP_Idinfo+RAND2))与 Sign
CIM(Hash(Content_ID+RAND2))组成串连信息向 DTS服务器获取相应的时间 戳, 该时间戳中包含了所有权变更的时间信息。用其他可以证明此次所有权 变更的信息获取时间戳也是可以的, 例如直接用上述歩骤中介绍的所有权变 更凭据 Hash (Excg— Info+RAND+Hash(CP— Idinfo+RAND2)获取, 还可以用 HasMRAND2;i获取等等, 获得时间戳后, CIM还可以将此时间戳存储在此次 所有权变更的内容的 CONTENT— ID对应的注册记录中,用以证明此次内容所 有权的变更。 以上的处理过程可以防止内容的所有者在不同的时间将内容的 所有权变更给多个受让者。
歩骤 406.CIM生成内容所有权变更成功或失败的信息发送给 CPT, 该信 息还可以发送给 COT。
以上实施例实现了由内容受让者终端 CPT向 CIM发起所有权变更请求, CIM处理完成内容所有权的变更。
本发明实施例提供一种由内容的所有者发起的内容所有权变更的处理 方法, 具体流程如附图 5所示。
歩骤 501. 内容所有者终端 COT接收内容受让者终端 CPT发送的受让请 求消息, 该受让请求消息中包含需要受让的内容或内容标识。 受让请求消息 中还包含 CPT生成的所有权置换随机数, 或加密隐藏后的所有权置换随机 数, 该受让请求消息中还可以包含内容受让者信息, 例如受让者身份的标识 可以是受让者的姓名, 组织名, ID等, 本实施例中内容受让者信息用 CP— IDinfo表示。 受让请求消息可以由 CPT根据如下过程生成, CPT将内容受 让者信息 CP— Idmfo, 以及上述随机数 RAND2组合形成串连信息,并计算此串 联信息的散列运算值得到 Hash CP— Idinfo+ RAND2), 根据上述得到 Hash(CP_Idinfo+ RAND2), 以及, 所需要受让内容的标识 CONTENT— ID, 内 容受让者信息 CP— Idinfo生成受让请求消息。
歩骤 502. 内容所有者的终端 COT在接收到 CPT发送的受让请求消息后 进行内部处理, COT可以根据所述受让请求消息中的内容或 CONTENT— ID, 判断该内容或该 CONTENT— ID所对应的内容的所有者是否为自身所有,若是 则进入歩骤 503继续处理。
歩骤 503.COT进一歩生成所有权变更请求, 该请求中包含了内容或内容 标识, 所有权置换随机数, 以及所有权变更凭据。 并将该请求发送到 CIM。 具体过程同歩骤 404中的描述相同。
歩骤 504. CIM在收到所有权变更请求后, 进行所有权变更的处理。 具体 过程同歩骤 405中的描述相同。
歩骤 505. CIM生成内容所有权变更成功或失败的信息发送给 CPT, 该信 息还可以发送给 COT。 具体过程同歩骤 406中的描述相同。
以上实施例实现了由内容所有者终端 COT向 CIM发起所有权变更请求, CIM处理完成内容所有权的变更。
本发明实施例提供的一种内容申诉的方法如附图 6所示, 其中
歩骤 601.内容的申述者认为 CIM中相关注册的内容为自身所有, 为此内 容的申述者通过内容申述者终端向内容 ID管理服务器 CIM发送申诉请求消 息, 该申诉请求消息中包含了所要申诉的内容, 用于申诉的第一时间戳, 该 时间戳可以用于证明其对相关内容所有权, 可以是在内容出现时, 申诉者通 过申述者的终端根据内容散列运算值 Hash(CONTENT)从 DTS服务器获取的 时间戳 TS (Hash(CONTENT)) , 该第一时间戳中包含了内容出现的时间信 息。 申诉请求消息中还可以包含所要申诉的内容在 CIM中对应的内容 ID。
歩骤 602.内容 ID管理服务器 CIM在收到申诉请求消息后根据申诉请求消 息中的需要申诉的内容, 以及时间戳进行处理。
例如, 内容 ID管理服务器 CIM从申诉请求消息中获取需要申诉的内容, 提取该内容的特征值, 将特征值和 CIM服务器中存储的内容的特征值进行比 较, 查找相同或相似的内容。 如果上述的申诉请求消息中携带的内容 ID, 则 CIM可以根据此内容 ID直接找相应的内容, 比较相应内容和申诉内容的特征 值, 确定内容是否一致或大体一致。 若找到了相同或相似内容, 则进一歩确 定存储的该相同或相似内容对应的第二时间戳, 该第二时间戳存储在 CIM 中。 判断第一时间戳中的时间晚于第二时间戳中的时间, 则申诉失败, 判断 第一时间戳中的时间早于第二时间戳中的时间, 申诉成功, CIM将注销相同 或相似的内容的注册, 可以是将相应的注册记录删除, 或者标记相应的注册 记录为无效。
歩骤 603.内容 ID管理服务器向申诉者的终端反馈申诉的结果, 该申诉结 果包含了此次申诉成功或失败的信息。在本发明的另一个实施例中, 内容 ID 管理服务器还可以进一歩向内容的原所有者的终端反馈申诉的结果。
以上实施例实现了对内容的申诉, 通过确定谁拥有该内容最早的出现时 间, 防止他人盗用内容进行注册。
