Embodiment
In order to make content of the present invention more cheer and bright, below in conjunction with accompanying drawing, the present invention is described in further detail.
The data access method that the present invention is based on cloud computing adopts Authentication mechanism, to guarantee the fail safe of client and high in the clouds line, only has high in the clouds to verify reliable client and the high in the clouds line of just allowing of identity of wish line client later.For this reason, need to preset access identity data, and save the data in high in the clouds.
The flow process of the default access identity data of the present invention is as shown in Figure 1:
Step S101: client sends the order of access identity data to high in the clouds.
Step S102: high in the clouds sends request default authenticated data order to client after receiving the order of access identity data.
Step S103: client sends default authenticated data to high in the clouds.
Step S104: the network address and the connectivity port of high in the clouds device obtained in high in the clouds.
Step S105: high in the clouds is by the above-mentioned network address, connectivity port also storage associated with default authenticated data.Suppose that default authenticated data is the character string of 8～16, so, these character strings can also store so that the mode shown in table 1 is associated with the network address, connectivity port.
Table 1 network address, connectivity port and default authenticated data incidence relation table
| Default authenticated data | The network address of high in the clouds device | The connectivity port of high in the clouds device |
| Character string 1 | 192.168.0.1 | 80801 |
| Character string 2 | 192.168.0.1 | 80802 |
| … | … | … |
Adopt the man-to-man interrelational form in the network address, connectivity port of this default authenticated data and high in the clouds device to form linked list, can reach the security requirement of client and high in the clouds line, and high in the clouds is corresponding rapidly effectively.
As mentioned above, once set up default authenticated data and the network address of high in the clouds device, after the incidence relation of connectivity port, the default corresponding client of authenticated data has just obtained the legal identity of using high in the clouds, can carry out the accessing operation of data, but before access data, need first to set up the line in client and high in the clouds.
The flow process of line method of operation of the present invention is as shown in Figure 2:
Step S201: client sends line order to described high in the clouds.
Step S202: high in the clouds sends request authenticated data order to client after receiving line order.
Step S203: client sends authenticated data to high in the clouds.
Step S204: whether high in the clouds comparison authenticated data is identical with default authenticated data, if so, enters step S205, if not, enters step S206.
Step S205: set up client and high in the clouds line.
Step S206: high in the clouds sends authentication failure message to client.
By above-mentioned steps, just the line in client and high in the clouds be can realize, storage or the extraction of data after this just can be carried out.
The present invention is based on cloud computing data access method flow process as shown in Figure 3:
Step S301, client transmission data storage or data reading order are to high in the clouds.
If high in the clouds receives data storage order:
Step S302, sends and receives data on file order to client.
Step S303, client transmits the feature data of data on file and data on file to high in the clouds.
Step S304, high in the clouds stores the feature data of data on file and data on file in personal information database.
If high in the clouds receives data reading order:
Step S305, sends request the order of feature data to client.
Step S306, client sends feature data to high in the clouds.
Whether step S307, there is data on file corresponding to feature data in high in the clouds search personal information database, if so, enters step S308, if not, finishes.
Step S308, data on file corresponding to feature data obtained in high in the clouds.
Step S309, high in the clouds sends data on file corresponding to feature data to client.
Step S310, client data on file corresponding to output characteristic data.For instance, feature data and corresponding data on file can adopt form as shown in table 2 to be stored in personal information database.
Table 2 feature data and data on file mapping table
| Feature data | Data on file |
| 2012, company's group photo | The photo document of company's group photo in 2012 |
| Recent film | The video documents of recent film |
| … | … |
Adopt this feature data mode associated with data on file by the data storage of needs storage beyond the clouds, greatly saved the memory space of client, and, feature data is all simple word or short sentence easy to remember, is convenient in client, to input these feature data at any time and just can extracts from high in the clouds.
