[0046]由于此实施例中,载体Cr与第一电子装置Dl彼此互为独立的装置,且载体Cr可用以储存代码Cd,故使用者可随身携带体积较小的载体Cr(例如为一卡片型载体、具有近场传输(NFC)功能之钥匙圈载体或一笔型载体),而无需携带整台第一电子装置Dl,即可将代码Cd利用前述的传输方式(例如图2中的步骤S230)传送到第二电子装置D2中。 [0046] For this embodiment, the carrier Cr and the first electronic device Dl independent of each other apparatus, and the carrier Cr may be used to store the code Cd, so that the user can carry a smaller volume of the support carrying the Cr (for example a card vectors, a near field transmission (NFC) function of a sum vector or key ring-type carrier), without carrying the whole of the first electronic device Dl, to code transmission using the aforementioned Cd (step 2 in FIG e.g. S230) to the second electronic device D2.

[0047]接着,以下进一步叙述文件传输方法400的各个步骤,为了方便说明,以下说明请一并参照图3至图4。 [0047] Next, the respective steps described further below file transfer method 400, for convenience of explanation, the following description please also refer to FIG. 3 to FIG. 图4根据本发明的一实施例绘示一种文件传输方法400的流程图。 FIG 4 according to an embodiment of the present invention shows a flowchart 400 of a file transfer method. 在此实施例中,步骤S410〜430皆与步骤S210〜S230相同,故此处不再赘述。 Embodiment, the steps are the same as step S410~430 S210~S230, it is not repeated here in this embodiment.

[0048] 在步骤S440中,第二电子装置D2传送代码Cd至云端系统110,且云端系统110验证代码Cd。 [0048] In step S440, the second electronic device transmits the code Cd to D2 cloud system 110, 110 and the cloud system authentication code Cd. 在一实施例中,代码Cd可以是用来描述加密档案Ef于云端系统110中所存放的档案存取路径(例如,加密档案Ef位于云端系统110中的某一服务器的某一文件夹)。 In one embodiment, the code Cd may be used to describe the encrypted file access path to the file Ef Drive system 110 are stored (e.g., encrypted file located in a file Ef Drive system 110 is a server folder). 当云端系统110接收到此代码Cd后,验证此档案存取路径下是否具有加密档案Ef;若云端系统110确认此档案路径下具有加密档案Ef,则视为验证成功;反之,若云端系统110确认此档案路径下不具有加密档案Ef,则视为验证失败,云端系统110会送出一警示讯息以通知第二电子D2此代码Cd验证失败。 When this cloud system 110 receives the code Cd, an encryption file to verify whether this file Ef access path; Drive system 110 checks if the file has the encrypted file Ef this path, it is considered successful verification; conversely, if the cloud system 110 encrypted file Ef does not have to confirm this file path is considered verification fails, cloud system 110 will send a warning message to inform the second electronic code Cd D2 validation fails.

[0049] 在另一实施例中,在步骤S420中,第一电子装置Dl可进一步设定云端系统110中用以存放加密档案Ef之档案夹(例如,加密档案Ef位于云端系统110中的第一文件夹)的访问权限。 [0049] In another embodiment, in step S420, the first electronic device Dl may be further configured Drive system 110 is used for storing clip files of encrypted files Ef (e.g., encrypted file located on Ef Drive system 110 a folder) access. 举例而言,使用者需要输入对应此档案夹之正确的账号(例如:uSerA)及密码(例如:1234),才可存取此档案夹(例如:第一文件夹)中的加密档案Ef。 For example, the user needs to enter the correct account number corresponding to this file folder of (e.g.: usera) and password (example: 1234), before access to this file folder (for example: a first folder) in the encrypted file Ef.

[0050] 更具体而言,在此实施例中,代码Cd可以是一组账号(例如:userA)及密码(例如:1234 ),当第二电子装置D2传送代码Cd至云端系统110后(步骤S440 ),云端系统110验证此代码Cd是否为对应此档案夹(例如:第一文件夹)之正确的账号及密码;当此代码Cd为对应此档案夹之正确的账号及密码时(即步骤S440所述的代码Cd为对应此档案夹的一组账号及密码,且此账号及密码与步骤S420所设定的对应此档案夹的账号及密码相同),云端系统110视为验证成功此代码Cd,并允许第二电子装置D2存取此档案夹中的加密档案Ef;反之,当此代码Cd不为对应此档案夹的正确的账号及密码时(即步骤S440所述的代码Cd为对应此档案夹的一组账号及密码,且此账号及密码与步骤S420所设定的对应此档案夹之账号及密码不相同),云端系统110视为验证失败,并送出一警示讯息告知第二电子D2此代码Cd验 [0050] More specifically, in this embodiment, the code may be a Cd group accounts (e.g.: userA) and password (example: 1234), when the second electronic device transmits the code Cd D2 to the cloud system 110 (step S440), the system cloud 110 verifies whether this code Cd folders corresponding to this (e.g.: first folder) of the correct account and password; Cd when this code corresponds to the correct account number and password of this file folder (i.e., step S440 Cd codes according to a set corresponding to this account and password file folders, and this account and the corresponding password set in step S420 folders this same account and password), the authentication is successful cloud system 110 deemed this code Cd, D2 and allows the second electronic device to access the encrypted files Ef this file folder; on the contrary, when the code is not Cd corresponds to the correct account and password, this file folder (i.e., the step S440 corresponds to the code Cd a set of folders in this account and password, and the account number and password in this step S420 and the set of folders corresponding to this account number and password are not the same), the verification fails considered cloud system 110, and sends a warning message to inform the second this code Cd D2 electronic test 失败,且不允许第二电子装置D2存取此档案夹中的加密档案Ef2。 Fails, the second electronic device and does not allow access to encrypted files D2 Ef2 this file folder.

[0051 ] 在步骤S450中,在云端系统110验证成功代码Cd后,第二电子装置D2由云端系统110下载与代码Cd相对应的加密档案Ef。 [0051] In step S450, after successful authentication codes 110 Cd cloud system, the second electronic device to download the code Cd D2 corresponding to the encrypted file by the cloud system 110 Ef. 在一实施例中,当代码Cd为用来描述加密档案Ef于云端系统110中所存放的档案存取路径时,云端系统110于验证成功代码Cd后,云端系统110允许第二电子装置D2由云端系统110下载相对应的加密档案Ef,例如:云端系统110开启某一档案夹或提供一下载连接,使第二电子装置D2可由云端系统110下载加密档案Ef。 In one embodiment the embodiment, when the code Cd is used to describe the file access path to the encrypted file Ef Drive system 110 are stored in the cloud system 110 to verify the success code Cd, cloud system 110 allows the second electronic device D2 Drive system 110 corresponding to the downloaded file Ef of encryption, for example: Drive system 110 provides open a folder or a file download link, D2 of the second electronic device 110 may download an encrypted file system Drive Ef.

[0052]在步骤S460中,在第二电子装置D2下载完成加密档案Ef后,云端系统110自动将储存于云端系统110中的加密档案Ef移除,并使代码Cd自动失效。 Encrypted File Ef [0052] In step S460, the second electronic device after the download is complete D2 Ef of encrypted files, the system cloud 110 is automatically stored in the cloud system 110 is removed, and the code Cd automatically expire.

[0053]在一实施例中,当代码Cd为用来描述加密档案Ef于云端系统110中所存放的档案存取路径时,当第二电子装置D2下载完成加密档案Ef后,云端系统110会自动将储存于云端系统110中的加密档案Ef移除。 After [0053] In one embodiment, when the code Cd is used to describe the file access path to the encrypted file Ef Drive system 110 are stored, a second electronic device when the download is complete D2 Ef encrypted file, the system cloud 110 automatically stored in the encrypted file 110 in the cloud system Ef removed.

[0054]在一实施例中,在第二电子装置D2下载完成加密档案Ef后,对应于此加密档案Ef的代码Cd亦自动失效,故即使云端系统110再次接收到代码Cd,使云端系统110会视为验证失败。 [0054] In one embodiment, the second electronic device after the download is complete D2 Ef encrypted file, encrypted file corresponding to this code is Cd Ef also automatically expire, so even if the cloud system 110 again receives the code Cd, so the system cloud 110 verification will be regarded as a failure.

[0055]此外,通过当第二电子装置D2下载完成加密档案Ef后,云端系统110自动将储存于云端系统110中的加密档案Ef移除,可以更确保此加密档案Ef不被其他第三人取得。 Encrypted File Ef [0055] Further, the electronic device when the second encrypted file Ef D2 after the download is complete, the system cloud 110 is automatically stored in the cloud system 110 is removed, can be more sure that this is not an encrypted file Ef other third achieved. 另一方面,若在第二电子装置D2下载完成加密档案Ef后,此加密档案Ef数据量庞大时,难以立刻完全被云端系统110移除之前,即使第三人取得代码Cd,由于此代码Cd已失效,此第三人也无法下载此加密档案Ef。 On the other hand, if the second electronic device after the download is complete D2 Ef encrypted file, the encrypted file Ef large amount of data, it is difficult to immediately completely removed before the cloud system 110, even if a third person codes Cd, since the code Cd has expired, this third person also can not download this file encryption Ef.

[0056]在步骤S470中,第二电子装置D2依据代码Cd以解密此加密档案Ef。 [0056] In step S470, the second electronic device based on the code Cd D2 to decrypt the encrypted file Ef. 于一实施例中,当代码Cd为档案之档案存取路径时,若将此档案存取路径视为一字符串或一串编码,并将其带入用以解密之算法后,则可将此加密档案Ef进行解密,以取得原始文件。 In one embodiment, when the code Cd is the file path of the file access, file access if this path seen as a string or a string encoding, and brought to the decryption algorithm can be the this encrypted file Ef is decrypted to obtain the original file.

[0057]在另一实施例中,第一电子装置Dl亦可将用以解密的密钥或用以解密之算法传送至载体Cr,故在步骤S430中,第二电子装置D2亦可通过通信连接取得储存于载体Cr中的解密密钥或解密算法,并将此解密密钥或解密算法应用于步骤S470中,以解密此加密档案Ef。 [0057] In another embodiment, the first electronic device Dl may be used to transmit the decryption key or decryption algorithm to the carrier Cr, so in step S430, the second electronic device through the communication may D2 obtaining a decryption key stored in the connection or the carrier Cr, a decryption algorithm, and this algorithm to the decryption key or decryption in step S470, to decrypt the encrypted file Ef. 然而,本领域具通常知识者应可得知,本发明可依实际系统设计情况,于步骤S420中选用适当的加密算法将原始文件进行加密,以利于步骤S470中将加密档案Ef顺利地进行解密。 However, those having ordinary knowledge should be known, as per the present invention, the system design, the choice of appropriate encryption algorithm in step S420 the original file is encrypted, it will facilitate the step S470 to decrypt the encrypted file Ef smoothly .

[0058]综上所述,本发明所示之文件传输系统及其方法通过将对应原始文件的代码纪录于方便一用户携带的载体中,并将原始文件加密后上传至云端系统,可让用户只携带一具有代码的载体,且此载体无需储存整个原始文件。 [0058] In summary, the file transfer system and method of the present invention is shown by the code corresponding to the original document record carrier in a conveniently carried by the user, and uploaded to the cloud system after the encrypted original file, allows the user a carrier having a carrying only code and store this vector without the entire original document. 此外,通过将原始文件经加密后再上传至云端系统,可强化原始文件在传输过程中的安全性,且当另一使用者取得此载体中的代码时,可依据此代码,从云端系统下载对应此代码之加密档案,并于使用者的本地(local)装置上解密此加密档案Ef。 Further, the original file is uploaded to the cloud system is then encrypted, security can be strengthened during transmission of the original document, and when the other users get the code of this carrier, whereby the code to follow, downloaded from the cloud system file corresponding encryption code, the local user and to the (local) means decrypts the encrypted file Ef.
