微爱帮监狱寄信邮票真伪核实接口认证方案-编程实验室

一、多重防伪识别接口

class StampVerificationAPI: """邮票真伪多重核验接口""" def __init__(self): self.scanners = { 'microprint': MicroprintScanner(), 'watermark': WatermarkDetector(), 'uv_light': UVScanner(), 'magnetic': MagneticSensor(), 'nfc': NFCReader() } # 监狱邮票特殊验证规则 self.prison_rules = { 'required_features': ['microprint', 'watermark', 'uv_mark'], 'min_security_level': 3, 'allowed_issuers': ['中国邮政', '司法部邮票中心'] } async def verify_stamp(self, stamp_image, physical_data): """ 邮票真伪核实 """ verification_results = [] # 1. 图像特征识别 image_features = await self.scan_image_features(stamp_image) # 2. 物理特征检测 physical_features = await self.scan_physical_features(physical_data) # 3. 多重验证算法 verification_results.append( await self.verify_by_microprint(stamp_image) ) verification_results.append( await self.verify_by_watermark(stamp_image) ) verification_results.append( await self.verify_by_uv_light(physical_data['uv_image']) ) if 'nfc_data' in physical_data: verification_results.append( await self.verify_by_nfc(physical_data['nfc_data']) ) # 4. 综合评分 authenticity_score = self.calculate_authenticity_score(verification_results) # 5. 司法验证记录 judicial_record = await self.create_judicial_record({ 'stamp_data': stamp_image, 'verification_results': verification_results, 'score': authenticity_score }) return { 'authentic': authenticity_score >= self.prison_rules['min_security_level'], 'authenticity_score': authenticity_score, 'verification_details': verification_results, 'judicial_record_id': judicial_record['id'], 'recommended_action': self.get_recommendation(authenticity_score) }

二、防伪特征检测

// 2. 邮票防伪特征检测 public class StampSecurityFeatureDetector { private static final double MIN_MATCH_SCORE = 0.85; public SecurityFeatures detectFeatures(MultipartFile stampImage) { SecurityFeatures features = new SecurityFeatures(); // 1. 微缩文字识别 features.setMicroprint( ocrService.detectMicroprint(stampImage, new MicroprintConfig() .setExpectedText("中国邮政") .setFontSize(0.1) // 0.1mm .setRequired(true)) ); // 2. 水印检测 features.setWatermark( imageProcessor.detectWatermark(stampImage, WatermarkPattern.PRISON_SPECIAL) ); // 3. 荧光油墨检测 features.setFluorescentInk( uvScanner.detectUVPattern(stampImage, UVPattern.STAMP_SECURITY) ); // 4. 雕刻版纹识别 features.setEngravingPattern( patternMatcher.matchEngraving(stampImage, EngravingTemplate.PRISON_2025) ); // 5. 纸张纤维分析 features.setPaperFiber( fiberAnalyzer.analyzePaper(stampImage) ); return features; } public boolean verifySecurityFeatures(SecurityFeatures features) { // 必须通过的特征检测 boolean requiredPassed = features.getMicroprint().isPassed() && features.getWatermark().isPassed() && features.getFluorescentInk().isPassed(); // 综合评分 double totalScore = calculateTotalScore(features); return requiredPassed && totalScore >= MIN_MATCH_SCORE; } private double calculateTotalScore(SecurityFeatures features) { double score = 0.0; // 微缩文字：25% score += features.getMicroprint().getConfidence() * 0.25; // 水印：20% score += features.getWatermark().getConfidence() * 0.20; // 荧光：15% score += features.getFluorescentInk().getConfidence() * 0.15; // 雕刻版纹：20% score += features.getEngravingPattern().getConfidence() * 0.20; // 纸张纤维：20% score += features.getPaperFiber().getConfidence() * 0.20; return score; } }

三、区块链存证接口

// 3. 邮票核验区块链存证 class BlockchainStampVerification { constructor() { this.contract = new ethers.Contract( process.env.STAMP_VERIFICATION_CONTRACT, StampVerificationABI, this.getSigner() ); this.ipfs = new IPFSClient(); } async recordVerification(verificationData) { // 1. 数据上链存证 const verificationHash = this.hashVerificationData(verificationData); // 2. 存储证据到IPFS const ipfsCid = await this.storeEvidenceToIPFS(verificationData); // 3. 调用智能合约记录 const tx = await this.contract.recordStampVerification({ verificationHash, ipfsCid, verifier: this.getVerifierAddress(), timestamp: Math.floor(Date.now() / 1000), prisonCode: verificationData.prisonCode, stampSerial: verificationData.stampSerial }); // 4. 生成司法存证证书 const certificate = await this.generateJudicialCertificate({ txHash: tx.hash, verificationData, ipfsCid }); return { transactionHash: tx.hash, blockNumber: tx.blockNumber, ipfsCid, certificate, verificationTimestamp: new Date().toISOString() }; } async verifyOnChain(stampSerial, prisonCode) { // 查询区块链上的核验记录 const records = await this.contract.getStampVerificationRecords( stampSerial, prisonCode ); // 验证链上数据一致性 const isConsistent = await this.verifyDataConsistency(records); // 计算可信度评分 const credibilityScore = this.calculateCredibilityScore(records); return { verificationCount: records.length, firstVerified: records[0]?.timestamp, latestVerified: records[records.length - 1]?.timestamp, isConsistent, credibilityScore, verificationHistory: records.map(r => ({ timestamp: new Date(r.timestamp * 1000), verifier: r.verifier, txHash: r.txHash })) }; } generateJudicialCertificate(data) { // 生成符合司法标准的存证证书 return { certificateId: `JUDICIAL-STAMP-${Date.now()}-${data.stampSerial}`, stampSerial: data.stampSerial, prisonCode: data.prisonCode, verificationTime: new Date().toISOString(), blockchainProof: { txHash: data.txHash, blockNumber: data.blockNumber, contractAddress: process.env.STAMP_VERIFICATION_CONTRACT }, evidenceStorage: { ipfsCid: data.ipfsCid, storageTime: new Date().toISOString() }, judicialSignature: this.signJudicialData(data), qrCode: this.generateCertificateQR(data) }; } }

四、邮政系统对接

# 4. 邮政邮票核验系统对接 class PostalStampVerification: def __init__(self): self.client = AsyncHttpClient() self.auth = PostalAuth() async def verify_with_postal_system(self, stamp_data): """ 对接中国邮政邮票核验系统 """ # 1. 获取邮政API令牌 token = await self.auth.get_postal_token() # 2. 调用邮票核验接口 response = await self.client.post( "https://api.postal.gov.cn/stamp/verify", json={ "stamp_code": stamp_data['code'], "serial_number": stamp_data['serial'], "issue_year": stamp_data['issue_year'], "category": "PRISON_COMMUNICATION", "verification_type": "full" }, headers={ "Authorization": f"Bearer {token}", "X-Postal-App-Id": "WEIAI_PRISON_2025", "X-Judicial-Auth": await self.get_judicial_auth() } ) if response.status == 200: result = response.json() # 3. 验证邮政返回的数据 is_valid = self.validate_postal_response(result) # 4. 记录核验日志 await self.log_postal_verification(stamp_data, result, is_valid) return { "postal_verified": is_valid, "postal_status": result.get("status"), "issue_info": result.get("issue_info"), "circulation_info": result.get("circulation_info"), "postal_record_id": result.get("record_id") } raise Exception(f"邮政核验失败: {response.status}") async def verify_stamp_circulation(self, stamp_serial): """ 核验邮票流通记录 """ # 查询邮票流通历史 response = await self.client.get( f"https://api.postal.gov.cn/stamp/circulation/{stamp_serial}", headers={ "Authorization": f"Bearer {await self.auth.get_postal_token()}", "X-Postal-App-Id": "WEIAI_PRISON_2025" } ) if response.status == 200: circulation_data = response.json() # 分析流通模式 analysis = self.analyze_circulation_pattern(circulation_data) # 检查异常流通 anomalies = self.detect_circulation_anomalies(circulation_data) return { "circulation_history": circulation_data, "circulation_analysis": analysis, "anomalies_detected": anomalies, "is_suspicious": len(anomalies) > 0 } return {"error": "无法获取流通记录"}

五、核验结果接口

// 5. 邮票核验结果API接口 interface StampVerificationResult { stampId: string; verificationId: string; isAuthentic: boolean; confidenceScore: number; verificationMethod: string[]; securityFeatures: SecurityFeature[]; blockchainProof: BlockchainProof; postalVerification?: PostalVerification; recommendations: Recommendation[]; timestamp: string; } class StampVerificationAPI { @Post('/api/stamp/verify') @RateLimit({ limit: 10, window: 60 }) // 每分钟10次 @RequireAuth() async verifyStamp( @Body() request: VerifyStampRequest ): Promise<ApiResponse<StampVerificationResult>> { // 1. 验证请求参数 const validation = await this.validateRequest(request); if (!validation.valid) { throw new BadRequestException(validation.errors); } // 2. 执行多重核验 const verifier = new StampVerificationEngine(); const verification = await verifier.verify(request.stampData); // 3. 生成核验证书 const certificate = await this.generateVerificationCertificate(verification); // 4. 记录核验日志 await this.logVerification({ request, verification, certificate, userId: request.userId, ip: request.ip }); // 5. 返回结果 return { success: true, data: { ...verification, certificate, apiVersion: '2.0', responseTime: Date.now() - request.timestamp } }; } @Get('/api/stamp/verification/:verificationId') @RequireAuth() async getVerificationResult( @Param('verificationId') verificationId: string ) { // 查询核验记录 const record = await this.db.stampVerifications.findUnique({ where: { verificationId }, include: { blockchainProof: true, securityFeatures: true, auditLogs: true } }); if (!record) { throw new NotFoundException('核验记录不存在'); } // 验证数据完整性 const integrity = await this.verifyDataIntegrity(record); return { ...record, dataIntegrity: integrity, verificationChain: await this.getVerificationChain(record) }; } @Post('/api/stamp/report/suspicious') @RequireAuth() async reportSuspiciousStamp( @Body() report: SuspiciousStampReport ) { // 记录可疑邮票报告 await this.db.suspiciousReports.create({ data: { ...report, reporterId: report.userId, reportedAt: new Date(), status: 'pending_review' } }); // 触发预警 await this.alertSecurityTeam(report); // 添加邮票到观察列表 await this.addToWatchlist(report.stampId); return { success: true, reportId: report.reportId, message: '已提交可疑邮票报告，安全团队将进行核查' }; } }
