With the continuous development of wearable devices, the smart market for children is gradually emerging, more and more brands to join the ranks of children's smart watch, 360 children's guardian, Sogou “ ” “ K; ” compass Angel; and recently released the glory of small children watch. Except besides there are many start-up team released smart watches such as cool as small Q, Abba Cho small a and so on, thus intelligent children watch market competition is more intense.
But the development of more than a year, children's watches in the positioning, call two basic functions on the homogenization of serious, the search can be seen on Baidu at least 5 brands claiming “ sales champion ”. More important is that the radiation, materials, design and other safety issues of children's watches are not industry standards, but also to many of the cottage products of children's watches, there are many security risks.
1 positioning holes
It is reported that a smart watch program based on the MTK system platform in the development process of the accident caused no small fluctuations in the industry. The discovery points, in Taobao sales of 32 children smart watches products have 13 models there are interface ultra vires vulnerabilities, the harm of high grade. The vulnerability affects the user's span is larger, can lead to more than one million children are hackers real-time monitoring, access to children's daily walking trajectory, real-time environment, etc..

Subsequently, the security of the smart device Team Numen team confirmed this discovery, they said, the attacker can exploit the vulnerability query smart watch connection server, traverse all customer information, and according to the corresponding ID directly to see the child's location, real-time monitoring of the child's physical coordinates, daily activities and environmental recordings.
Team *Numen team is mainly focused on smart home, the Internet of things, wearable devices security research.

Once claimed to provide parents with children “ safety ” positioning and monitoring capabilities of children's smart watches, but now it is found that there is a huge security risk, especially the object is still a lack of self defense capabilities of children, is indeed worrying. You can imagine, if the above information is the key in the use of harbour evil designs will bring, extremely serious consequences. Previously, when our children were outdoors, they were randomized to have an accident; now, it is possible to be more specific and purposeful.
2 mobile phone network license
360 children watch the head Zhao Jun said:
“ most of China's campus is to prohibit the kids with a mobile phone, watch the future is playing children's ‘ mobile ’ function, the competition in the mobile phone is so fierce, the gross margin is almost zero, the watch is also manufacturers new profit contribution points. ”
Also because of this, in addition to positioning, watches have to add a lot of differences.

But as a &ldquo ” mobile phone; children watch, but couldn't get the mobile phone network license.
& ldquo; the current network license has two kinds of products, a mobile phone and a is a wireless terminal equipment, watches are later to apply for permits. ” hardware expert Su Peng said, the phone needs to be produced in advance, the general application requires 1-3 months, and wireless terminal equipment is mainly defined as the router and the like products, no contact with the human body, without the SAR (human exposure to RF electromagnetic fields of thermal effect) standard test, simply submit sample testing will soon be approved. This also reduces the cottage manufacturers to participate in the threshold, leading to security risks.
In addition, although the wireless terminal network license problems, but more "Shanzhai" is connected to the wireless terminal qualifications did not apply. Hardware expert Su Peng suggested that parents in the purchase of products, the device model input to the Ministry of telecommunications equipment into the network management center to check whether it has a license.
3 radiation intensity
At present, the positioning signal mainly has four kinds of GSM, Wifi, GPS and the near field (Bluetooth). Hardware expert Su Peng said:
The watch size is smaller than the cell phone, which naturally leads to the increase of its transmitting power, and the radiation is stronger. There are monitoring found that the standby state of the power intensity of the children watch a thousand times more than the phone. GPS can not be used indoors, and can not add communication function; in contrast, the GSM can cover the interior, while the cost is relatively low, is the mainstream of the children's watch, but its radiation is also the highest.
Manufacturers also note this. “ GSM if it continues to work, it is really bad for kids. ” 360 children watch responsible person Zhao Jun said, 360 using the intermittent type management (positioning), such as static state for 1 hours to play a point, the state of motion may be 5 minutes to play a point to avoid continuous work. “ at the same time, if the use of GPS in the outdoor, indoor is preferred to use WiFi, GSM. & rdquo; the position of the antenna is to be considered as compared to the strap and the bottom, the embedded dial can reduce the extent of radiation, such as glory small K and 360 children's guardian as is the operating.
