The invention discloses an anonymous method for preventing an attack of a labeled neighbor in social network dynamic release. A design algorithm based on neighbor label similarity is used for distributing nodes into proper groups, meanwhile neighbor structure and degree information of the nodes in the same group in an original social network is also considered, an used StruSim method is improved based on the algorithm, and thus the privacy requirement is met; structural similarity of the nodes in the group is improved to be ready for an next operation, and thus a social network chart after t moment grouping is acquired by using the method. The chart structure is changed by a random disturbing method, edges are randomly added or deleted, then a fuzzy method is used, each edge has the corresponding probability of existing in the social network, so that the probability of an attacker for uniquely determining an individual with a sensitive label is not more than 1/l. According to the method, only the labeled neighbor information with the sensitive label is disturbed, so that the quantity of undetermined charts is reduced, and data availability is improved.

From inner BE gateway server through SSL, firewall channel builds connection with FE gateway server. When client access end sends an access request to user at computer terminal, the information of request is encrypting packed by a service program at FE gateway server first. Next, through SSL connection, the packed information is transmitted to BE gateway server. Then, Unpacked by service program at BE gateway server, information is sent to user at computer terminal. After receiving the access information from the client access end, user at computer terminal sends out response information to the client access end through following steps: the response information is encrypting packed by a service program at BE gateway server first. Next, through SSL connection, the packed information is transmitted to FE gateway server. Then, unpacked by service program at FE gateway server, the response information is sent to the client access end.

The invention discloses a plant allocation method used for hollowed fence inner side greening. Key points of a technical scheme of the method are that plant combination allocation is divided into A, B, and C layers according to different height levels; B-layer planting stocks are close to a fence D; A-layer planting stocks are planted on the outer side of the B-layer planting stocks; and C-layer planting stocks are fully planted on a lower layer of the A-layer planting stocks. Plant allocated on the same A layer is any one selected from phyllostachys iridescens, phyllostachys bumbusoides, phyllostachys propinqua, phyllostachys violascens, phyllostachys aureosulcata, and phyllostachys heteroclada. Plant allocated on the same B layer is any one selected from euonymus japonicus column, euonymus japonicus column, viburnum odoratissimum column, and photinia fraseri column. Plant allocated on the same C layer is any one selected from fatsia japonica, aucuba japonica, and nandina domestica. With the application of the plant allocation, resident privacy requirements can be satisfied, and an ecological living space with senses of belonging and comfort can be built. The plant allocation also has a noise-reducing function. With the method, a high-efficiency energy-saving city residential area noise-reducing plant mode can be created.
